Description

La présente invention concerne un commutateur électrique et, plus particulièrement, un commutateur formant un ensemble de commutation électrique, notamment pour la commande des équipements et accessoires à bord des automobiles.The present invention relates to an electrical switch and, more particularly, a switch forming an electrical switching assembly, in particular for controlling equipment and accessories on board automobiles.

On sait que des équipements et accessoires électriques de plus en plus nombreux sont montés à bord des automobiles et que le fonctionnement de certains d'entre eux est maintenant géré par des circuits électroniques de gestion de commande. C'est ainsi qu'on peut prévoir, par exemple, une temporisation électronique, une commande par appui fugitif sur une touche de commutateur, une sélection de plusieurs fonctions, une commande progressive par impulsions, la détection et la prise en compte de divers paramètres, etc.We know that more and more electrical equipment and accessories are installed on board automobiles and that the operation of some of them is now managed by electronic control management circuits. Thus, for example, an electronic delay can be provided, a command by fleeting pressing of a switch key, a selection of several functions, a progressive command by pulses, the detection and taking into account of various parameters. , etc.

Des exemples d'application sont la commande automatique des lève-vitres ou la commande d'une lunette arrière chauffante avec temporisation.Examples of application are the automatic control of the window regulators or the control of a heated rear window with time delay.

Les ensembles de commande pour de tels appareils comprennent ainsi trois éléments : un organe manuel de commutation pour courants faibles ou commutateur proprement dit -une partie électronique de gestion de fonction- des organes de commutation en courants élevés ou circuit de puissance (relais) pour commander la charge.The control assemblies for such devices thus comprise three elements: a manual switching device for low currents or actual switch - an electronic part for managing the function - switching devices for high currents or power circuit (relay) for controlling load.

Ceci a eu pour effet d'introduire des connexions et un câblage de liaison, dit connectique, important entre les éléments constituant l'ensemble des commutations, donc d'un coût relativement élevé par rapport aux organes eux-mêmes, notamment lorsqu'il s'agit de commandes unitaires et de fonctions simples.This had the effect of introducing connections and connection wiring, known as connectivity, between the elements constituting the set of switches, and therefore of a relatively high cost compared to the members themselves, in particular when s '' are unitary commands and simple functions.

Par ailleurs, le montage de cette connectique à bord de l'automobile prend un certain temps de main-d'oeuvre et l'existence de liaison avec "connectique" est un facteur de limitation du niveau de fiabilité.Furthermore, mounting this connector on board the automobile takes a certain amount of manpower and the existence of a connection with "connector" is a factor limiting the level of reliability.

Un commutateur perfectionné de ce type est décrit dans le brevet No 86 13 740 déposé le 2 octobre 1986 au nom de la demanderesse.An improved switch of this type is described in patent No 86 13 740 filed on October 2, 1986 in the name of the applicant.

Toutefois, il n'est pas totalement adapté pour l'actionnement d'une vitre électrique de véhicule selon deux modes de fonctionnement, l'un, manuel, par maintien de la touche de commande, l'autre, automatique, par appui impulsionnel.However, it is not entirely suitable for actuating an electric vehicle window according to two operating modes, one, manual, by holding the control button, the other, automatic, by impulse pressing.

Les commutateurs assurant la double fonction décrite ci-dessus existent déjà et ils mettent en oeuvre, pour l'obtention du "point dur" ou passage d'un premier mode au second mode de fonctionnement, un effet de rampe avec discontinuité. La première course est réalisée soit avec une rampe, soit au moyen d'un mécanisme classique du type à rupture brusque avec déclic, dérivant d'appareils monocourse existants. La deuxième course est également réalisée avec une rampe ce qui ne permet pas l'obtention d'un effet tactile de déclic avec faible course.The switches ensuring the double function described above already exist and they implement, for obtaining the "hard point" or transition from a first mode to the second operating mode, a ramp effect with discontinuity. The first race is carried out either with a ramp or by means of a conventional snap-action mechanism with click, derived from existing single-stroke devices. The second race is also carried out with a ramp which does not make it possible to obtain a tactile click effect with a short stroke.

La possibilité d'une deuxième course au moyen d'un contact cloquant fut également envisagée par des équipementiers, mais elle reste associée à un mécanisme volumineux et coûteux pour une commutation en courant faible.The possibility of a second stroke by means of a blistering contact was also considered by equipment manufacturers, but it remains associated with a bulky and expensive mechanism for switching to low current.

Dans d'autres applications, il a été proposé des microrupteurs à poussoir comportant deux contacts cloquants disposés l'un au-dessus de l'autre, et susceptibles d'être soudés sur un circuit imprimé. Toutefois, leurs performances tactiles sont réellement faibles et leur encombrement et leur coût sont tels qu'ils n'ont pas pu être utilisés pour la commande de plusieurs modes de fonctionnement.In other applications, push-button microswitches have been proposed comprising two blistering contacts arranged one above the other, and capable of being soldered on a printed circuit. However, their tactile performance is really low and their size and cost are such that they could not be used for controlling several operating modes.

La présente invention a pour but de proposer un commutateur qui soit simple à fabriquer malgré le nombre de pièces qu'il peut inclure et avec un coût relativement faible comparé aux commutateurs existants, tout en ayant des performances supérieures.The present invention aims to provide a switch which is simple to manufacture despite the number of parts it can include and with a relatively low cost compared to existing switches, while having superior performance.

La présente invention a pour objet un commutateur électrique, du type comprenant un organe manuel de commande qui est articulé à pivotement sur un boîtier dans lequel est monté un circuit électrique d'interconnexion dont au moins une fonction de commande est assurée par au moins un contact cloquant, et il est caractérisé en ce qu'il comporte au moins deux contacts cloquants disposés sensiblement dans un même plan et actionnés l'un après l'autre par un organe d'actionnement qui est interposé entre lesdits contacts cloquants et ledit organe manuel de commande.The present invention relates to an electric switch, of the type comprising a manual control member which is pivotally articulated on a housing in which is mounted an electrical interconnection circuit of which at least one control function is ensured by at least one contact. blistering, and it is characterized in that it comprises at least two blistering contacts arranged substantially in the same plane and actuated one after the other by an actuating member which is interposed between said blistering contacts and said manual member of ordered.

Un avantage de la présente invention réside dans le fait qu'on obtient un effet tactile de déclic avec faible course de l'organe manuel de commande du commutateur.An advantage of the present invention lies in the fact that a tactile tactile effect is obtained with a short stroke of the manual control member of the switch.

Suivant une autre caractéristique de l'invention, le commutateur comporte quatre contacts cloquants disposés sensiblement dans un même plan et coopérant chacun avec un pion de contact d'un palonnier qui est monté flottant entre l'organe de commande manuelle et lesdits contacts cloquants. De cette manière, on peut commuter soit des courants faibles, de l'ordre de 10 à 100 mA, soit des courants plus élevés, par exemple les relais internes au commutateur. Toutefois, les contacts, suivant la logique de fonctionnement retenue, sont susceptibles de commuter des courants encore plus élevés pour actionner le moteur d'un lève-vitre, par exemple.According to another characteristic of the invention, the switch comprises four blistering contacts arranged substantially in the same plane and each cooperating with a contact pin of a spreader which is mounted floating between the manual control member and said blistering contacts. In this way, it is possible to switch either low currents, of the order of 10 to 100 mA, i.e. higher currents, for example the internal relays of the switch. However, the contacts, depending on the operating logic adopted, are capable of switching even higher currents to activate the motor of a window regulator, for example.

De plus, le commutateur à touche unique permet, par une double course, de sélectionner l'un des deux modes de fonctionnement dans chaque sens, lorsqu'il équipe un dispositif de lève-vitre.In addition, the one-touch switch allows, by a double stroke, to select one of the two operating modes in each direction, when fitted to a window regulator.

D'autres caractéristiques et avantages apparaîtront à la lecture de la description d'un mode de réalisation particulier de l'invention, ainsi que des dessins annexés sur lesquels :Other characteristics and advantages will appear on reading the description of a particular embodiment of the invention, as well as the appended drawings in which:

Le commutateur électrique représenté sur les figures 1 à 3 comprend un organe manuel de commande ou touche de commande 1 qui est montée pivotante en son centre sur deux axes de pivotement 2 prévus sur les côtés latéraux 3 d'un boîtier 4, lesdits axes de pivotement 2 déterminant un axe de basculement 2′. La touche de commande 1 comprend des orifices 5 pour le passage des axes de pivotement 2, et des flèches 6 éclairées indiquant le mode de fonctionnement du commutateur, la flèche de droite pour la descente et la flèche de gauche pour la montée d'une vitre par exemple. La touche de commande 1 qui est moulée avec un insert translucide pour l'éclairage des flèches 6, est rendue solidaire du boîtier 4 par clipsage par exemple, de la manière indiquée dans le brevet cité en référence.The electrical switch shown in Figures 1 to 3 comprises a manual control member or control button 1 which is pivotally mounted in its center on two pivot axes 2 provided on the lateral sides 3 of a housing 4, said pivot axes 2 determining a tilt axis 2 ′. The control button 1 comprises orifices 5 for the passage of the pivot axes 2, and illuminated arrows 6 indicating the operating mode of the switch, the right arrow for the descent and the left arrow for the raising of a window for example. The control button 1 which is molded with a translucent insert for lighting the arrows 6, is made integral with the housing 4 by clipping for example, in the manner indicated in the patent cited in reference.

Un conduit diffuseur 7 est monté solidaire de la touche de commande et comporte un logement 8 pour une zone émettrice 9 d'un composant d'éclairage 10. Il est possible d'utiliser tout type de composant d'éclairage tel qu'une mini-lampe à filament, une diode électro-luminescente associée à une résistance en série ou encore une diode électro-luminescente avec résistance incorporée. Le raccordement sur un circuit électrique d'interconnexion, peut être effectué par douille amovible ou par soudure, soit comventionnellement avec composants à queues, soit par montage en surface avec des composants qu'on appelle des "chips".A diffuser duct 7 is mounted integral with the control button and includes a housing 8 for an emitting area 9 of a lighting component 10. It is possible to use any type of lighting component such as a mini filament lamp, an electroluminescent diode associated with a resistor in series or an electroluminescent diode with incorporated resistance. The connection to an electrical interconnection circuit can be carried out by removable socket or by welding, either conventionally with tail components, or by surface mounting with components called "chips".

Le palonnier 11 comporte au moins un pion de contact et, de préférence, deux pions de contact 12 qui sont alignés mais décalés d'un même côté par rapport à l'axe de symétrie longitudinal 13 du palonnier, lesdits pions de contact étant situés sur la face 14 en regard du diffuseur de lumière 7. Sur l'autre face du palonnier, sont prévus au moins deux pions d'actionnement et, de préférence, quatre pions d'actionnement 15 lorsqu'on utilise quatre contacts cloquants, comme décrits ci-après. Chacun des pions d'actionnement étant situé au-dessus et coopérant avec un contact cloquant, deux des quatre pions d'actionnement sont visibles sur la figure 1. Deux pions d'actionnement sont rigides et les deux autres peuvent travailler en flexion pour faire varier éventuellement la course au deuxième contact avec le contact cloquant correspondant, à la manière d'un bras élastique. Le palonnier 11 comprend des doigts de centrage et de guidage 16 qui se logent dans des logements correspondants 17 ménagés dans le boîtier 4.An actuating member constituted by a leveler 11, is mounted floating in the housing 4, below the diffuser duct 7. The lifter 11 comprises at least one contact pin and, preferably, two contact pins 12 which are aligned but offset by same side with respect to the longitudinal axis of symmetry 13 of the lifter, said contact pins being located on the face 14 facing the light diffuser 7. On the other face of the spreader, at least two actuation pins are provided and preferably four actuating pins when four blistering contacts are used, as described below. Each of the actuating pins being situated above and cooperating with a blistering contact, two of the four actuating pins are visible in FIG. 1. Two actuating pins are rigid and the other two can work in bending to vary possibly the race for the second contact with the corresponding blistering contact, in the manner of an elastic arm. The lifting beam 11 comprises centering and guiding fingers 16 which are housed in corresponding housings 17 formed in the housing 4.

Les pions de contact 12 sont alignés suivant un axe longitudinal 13′ qui est parallèle à l'axe de symétrie 13, les deux axes longitudinaux 13 et 13′ étant situés dans un même plan horizontal. Le décalage X entre les axes 13 et 13′ permet de fixer l'effet différentiel qui sera décrit à propos de la figure 9.The contact pins 12 are aligned along a longitudinal axis 13 ′ which is parallel to the axis of symmetry 13, the two longitudinal axes 13 and 13 ′ being located in the same horizontal plane. The offset X between the axes 13 and 13 ′ makes it possible to fix the differential effect which will be described with reference to FIG. 9.

Le palonnier 11 est symétrique dans le cas d'un mécanisme double effet dans les deux sens d'actionnement de la touche de commande 1. Dans certains cas, une seule commutation est possible pour un sens d'actionnement avec un seul pion d'actionnement associé à un seul contact cloquant. Il en est ainsi, notamment, pour un actionnement manuel ou automatique avec discrimination par le temps. Un orifice 18 est ménagé au centre du palonnier pour permettre le passage de la lampe d'éclairage 10 ou de des organes de connexion électrique.The lifter 11 is symmetrical in the case of a double-acting mechanism in both directions of actuation of the control key 1. In certain cases, only one switching is possible for an actuation direction with a single actuation pin associated with a single blistering contact. This is particularly the case for manual or automatic actuation with time discrimination. An orifice 18 is provided in the center of the lifter to allow the passage of the lighting lamp 10 or of electrical connection members.

Une lame élastique 19 peut éventuellement être disposée entre le conduit diffuseur 7 et le palonnier 11. La lame élastique 19 comporte deux bras souples 20 munis chacun d'un pion de clipsage 21 qui vient se clipser dans un logement approprié 22 ménagé sur le côté latéral du conduit diffuseur 7. La lame élastique 19 est réalisée dans de l'acier ressort et elle permet le rappel de la touche de commande 1 avec rattrapage des jeux et elle définit, par son jeu au point de contact par rapport à ladite touche 1, la course d'actionnement au premier contact cloquant. La lame élastique 19 réalise également un armage entre la touche 1 et le palonnier 11.An elastic blade 19 may optionally be disposed between the diffuser duct 7 and the lifter 11. The elastic blade 19 comprises two flexible arms 20 each provided with a clipping pin 21 which is clipped into an appropriate housing 22 formed on the lateral side of the diffuser duct 7. The elastic blade 19 is made of steel spring and it allows the recall of the control button 1 with backlash and it defines, by its play at the point of contact with respect to said button 1, the actuating stroke at the first blistering contact. The elastic blade 19 also performs a winding between the key 1 and the lifter 11.

Les contacts cloquants susceptibles d'être utilisés dans le commutateur selon la présente invention sont représentés sur les figures 4 à 9.The blistering contacts which can be used in the switch according to the present invention are shown in FIGS. 4 to 9.

Sur les figures 4 et 5 est représenté un contact cloquant 23 qui se présente sous la forme d'une petite coupelle légèrement bombée et dont les quatre côtés sont découpés en 24. Le contact cloquant repose sur le circuit électrique d'interconnexion 25, représenté sur les figures 2 et 3, par quatre coins 26 dont les bords externes 27 sont légèrement relevés, comme cela est visible sur la figure 5. Une petite dépression 28 est ménagée au centre du contact cloquant pour amorcer la déformation de ce dernier lorsque le point d'actionnement correspondant du palonnier 11 exerce un effort sur ledit contact cloquant. Le diagramme course-effort du contact cloquant 23 est représenté sur la figure 8a.In FIGS. 4 and 5 is shown a blistering contact 23 which is in the form of a small slightly curved cup and the four sides of which are cut at 24. The blistering contact rests on the electrical interconnection circuit 25, represented on Figures 2 and 3, by four corners 26 whose outer edges 27 are slightly raised, as can be seen in Figure 5. A small depression 28 is formed in the center of the blistering contact to initiate the deformation of the latter when the point d 'corresponding actuation of the lifter 11 exerts a force on said blistering contact. The stroke-force diagram of the blistering contact 23 is shown in FIG. 8a.

Le contact cloquant 29 représenté sur la figure 6 présente des côtés latéraux 30 davantage dépouillés que ceux du contact cloquant 23. Dans ce mode de réalisation, les rebords externes 31 ne sont pas relevés mais plats. Le diagramme course-effort du contact cloquant 29 est représenté sur la figure 8b.The blistering contact 29 shown in FIG. 6 has lateral sides 30 more stripped than those of the blistering contact 23. In this embodiment, the external flanges 31 are not raised but flat. The stroke-force diagram of the blistering contact 29 is shown in FIG. 8b.

Les contacts cloquants décrits ci-dessus assurent une très faible course d'actionnement avec effet tactile et sont réalisés pour procurer un effet de déclic. La nature de la matière utilisée dépend de l'effet tactile désiré et leur disposition peut varier suivant la construction, une disposition particulière est représentée sur la figure 1 et comprenant les contacts cloquants 23 représentés sur les figures 4 et 5.The blistering contacts described above ensure a very short actuating stroke with effect tactile and are made to provide a click effect. The nature of the material used depends on the desired tactile effect and their arrangement may vary depending on the construction, a particular arrangement is shown in FIG. 1 and comprising the blistering contacts 23 shown in FIGS. 4 and 5.

Une matière intéressante est l'inox mais d'autres matières à base de cuivre-beryllium peuvent être utilisées. En fonction des courants à commuter, on peut revêtir l'inox par dorure ou argenture. Par exemple, pour de très faibles courants à commuter, on utilisera un revêtement de 0,2 mm d'or, tandis que pour des courants supérieurs à 100 mA, on utilisera un revêtement de 0,002 mm d'argent.An interesting material is stainless steel but other materials based on copper-beryllium can be used. Depending on the currents to be switched, stainless steel can be coated with gilding or silvering. For example, for very low switching currents, a coating of 0.2 mm gold will be used, while for currents greater than 100 mA, a coating of 0.002 mm silver will be used.

On peut également associer entre eux deux types de contacts cloquants différents, ainsi que cela est représenté sur la figure 7. Le contact cloquant 29 assure par exemple la commutation des courants faibles et le contact cloquant 23 assurant la commutation de courants élevés, ceux des relais notamment.It is also possible to associate two different types of blistering contacts together, as shown in FIG. 7. The blistering contact 29 ensures, for example, the switching of low currents and the blistering contact 23 ensuring the switching of high currents, those of the relays. especially.

On peut également utiliser un contact cloquant 32 comme celui représenté sur la figure 9, et dont les pattes 33 sont pourvues chacune d'un picot de liaison 34 pour montage en traversée du circuit d'interconnexion 25, avec soudure éventuelle.It is also possible to use a blistering contact 32 like that shown in FIG. 9, and the legs 33 of which are each provided with a connecting pin 34 for mounting through the interconnection circuit 25, with possible soldering.

Un film protecteur 35, du type adhésif résistant tel que celui connu sous la dénomination KAPTON, est disposé au-dessus des contacts cloquants, ce qui permet de les immobiliser sur le circuit 25, tout en assurant une protection aux pollutions.A protective film 35, of the resistant adhesive type such as that known under the name KAPTON, is placed above the blistering contacts, which makes it possible to immobilize them on the circuit 25, while ensuring protection against pollution.

Dans le cas de contacts cloquants 32 à picots 34, le film protecteur 35 n'assure plus qu'une éventuelle fonction de protection à la pollution puisque les picots assurent la liaison avec le circuit 25. Dans ces conditions, on peut le remplacer avantageusement par une nappe de mousse du type polyuréthane intercalée entre le palonnier 11 et les contacts cloquants. Bien évidemment, la mousse peut être adhésive ou non.In the case of blistering contacts 32 with pins 34, the protective film 35 only provides a possible pollution protection function since the pins ensure the connection with the circuit 25. Under these conditions, it can advantageously be replaced by a polyurethane type foam sheet interposed between the lifter 11 and the blistering contacts. Obviously, the foam can be adhesive or not.

Le circuit électrique d'interconnexion 25 est un circuit imprimé simple face comportant des zones de contact qui sont revêtues d'un étamage type Sn, Pb, Ni ou Au. Le circuit 25 assure les liaisons électriques par soudure ou sertissage entre les contacts cloquants et les bornes de sortie du commutateur, ainsi que le raccordement de la fonction éclairage de la touche de commande 1. Le circuit 25 est guidé, comme le palonnier 11, par un évidement intérieur du boîtier 4 et s'appuie sur des bossages 36 issus du fond connecteur 37.The electrical interconnection circuit 25 is a single-sided printed circuit comprising contact zones which are coated with tinning of Sn, Pb, Ni or Au type. The circuit 25 provides the electrical connections by soldering or crimping between the blistering contacts and the switch output terminals, as well as the connection of the lighting function of the control button 1. The circuit 25 is guided, like the lifting beam 11, by an interior recess of the housing 4 and rests on bosses 36 coming from the connector bottom 37.

Le connecteur 37 est une pièce plastique moulée et constitue avec le circuit et les contacts cloquants, un sous-ensemble d'interconnexion et de commutation indépendant qui est monté et testé isolément. L'assemblage du connecteur 37 sur le boîtier 4 s'effectue par clipsage de tétons 38 dans des évidements 39 du boîtier 4.The connector 37 is a molded plastic part and constitutes with the blistering circuit and contacts, an independent interconnection and switching sub-assembly which is mounted and tested in isolation. The connector 37 is assembled on the housing 4 by clipping studs 38 into recesses 39 in the housing 4.

On peut, si on le désire, surmouler dans le connecteur 37 des zones de contact pour les contacts cloquants afin de réaliser un circuit électrique et supprimer, de ce fait, le circuit 25 et les liaisons soudées.It is possible, if desired, to overmold in the connector 37 the contact zones for the blistering contacts in order to produce an electrical circuit and thereby suppress the circuit 25 and the soldered connections.

Il est également possible d'interposer une grille de connexion 40 (figure 10), obtenue à l'aide d'un outil de découpe-formage, et dans laquelle les pistes 41 sont reliées au moyen de pontets 42. La grille 40 possède à la fois des extrémités avec picots pour soudure sur le circuit 25 et des lames 43, de section carrée, pour des broches de sortie. Les lames 43 sont insérées dans le connecteur 37, lors du montage.It is also possible to interpose a connection grid 40 (FIG. 10), obtained using a cutting-forming tool, and in which the tracks 41 are connected by means of bridges 42. The grid 40 has at both ends with pins for soldering on circuit 25 and blades 43, of square section, for output pins. The blades 43 are inserted into the connector 37, during assembly.

Enfin, la grille de connexion 40 peut être surmoulée lors du montage du connecteur 37.Finally, the connection grid 40 can be overmolded during assembly of the connector 37.

Le fonctionnement du commutateur selon l'invention, décrit ci-après, concerne un commutateur pour lève-vitre, à double course.The operation of the switch according to the invention, described below, relates to a switch for window regulator, with double stroke.

Un effort exercé sur la touche de commande 1 (figure 1) provoque, par appui sur le point de contact 12, à droite sur la figure 1, le pivotement du palonnier 11. Cela amène le pion d'actionnement 15 à s'appuyer sur le contact cloquant 23b, de manière à le déformer et à réaliser une commutation de courant, faible par exemple. Une pression supérieure sur la touche de commande assure la commutation au deuxième étage par basculement latéral du palonnier, en raison de l'excentricité des points de contact par rapport à l'axe longitudinal 13, et pression conséquente de l'autre pion d'actionnement sur le contact cloquant 23a; les contacts cloquants 23a et 23b constituant une paire de contacts qui assurent le double effet avec deux efforts de manoeuvre différents pour un même sens d'actionnement de la touche de commande 1. L'autre paire de contacts cloquants 23′a et 23′b assurent le double effet pour l'autre sens d'actionnement, gauche sur la figure 1, de la touche de commande 1.A force exerted on the control button 1 (FIG. 1) causes, by pressing on the contact point 12, on the right in FIG. 1, the pivoting of the lifter 11. This causes the actuating pin 15 to be pressed on the blistering contact 23b, so as to deform it and to carry out a switching of current, weak for example. A higher pressure on the control key ensures switching to the second stage by lateral tilting of the lifting beam, due to the eccentricity of the contact points relative to the longitudinal axis 13, and consequent pressure of the other actuation pin on the blistering contact 23a; the blistering contacts 23a and 23b constituting a pair of contacts which provide the double effect with two different operating forces for the same direction of actuation of the control button 1. The other pair of blistering contacts 23′a and 23′b provide the double effect for the other direction of actuation, left in FIG. 1, of the control button 1.

Les deux contacts cloquants de chaque paire sont disposés côte à côte et leur axe d'alignement est parallèle à l'axe de basculement 2′ de la touche de commande 1 lorsque la configuration est en rectangle.The two blistering contacts of each pair are arranged side by side and their alignment axis is parallel to the tilt axis 2 ′ of the control button 1 when the configuration is in rectangle.

Les quatre contacts cloquants 23a, 23b et 23′a et 23′b sont disposés sensiblement dans un même plan horizontal et symétriquement par rapport aux deux axes de symétrie, suivant une configuration en rectangle. Il va de soi que d'autres configurations peuvent être adoptées telles qu'une configuration en V ou en trapèze.The four blistering contacts 23a, 23b and 23′a and 23′b are arranged substantially in the same horizontal plane and symmetrically with respect to the two axes of symmetry, in a rectangle configuration. It goes without saying that other configurations can be adopted such as a V or trapezoid configuration.

Lorsque la pression exercée sur la touche de commande 1 cesse, la lame élastique 19 ramène ladite touche de commande vers sa position de repos. Les cloquants reprennent leur position de repos les uns après les autres au fur et à mesure que cesse sur eux l'action du palonnier ou de la touche de commande lorsqu'elle est ramenée à sa position neutre.When the pressure exerted on the control button 1 ceases, the elastic blade 19 returns said control button to its rest position. Blistering return to their rest position one after the other as the action of the lifter or the control button ceases when they are brought back to their neutral position.

Le diagramme effort-course relatif à la touche de commande 1 est représenté sur la figure 9.The force-stroke diagram relating to the control button 1 is shown in FIG. 9.

L'effort exercé sur la touche de commande 1 en un endroit situé à 14 mm environ de l'axe de pivotement de ladite touche, est de l'ordre de 4,5 N pour une course d'environ 1,25 mm (point A) lorsque le premier cloquant, par exemple le plus faible, en l'occurrence le cloquant 29 de la figure 7, est actionné.The force exerted on the control key 1 at a location located approximately 14 mm from the pivot axis of said key, is of the order of 4.5 N for a stroke of approximately 1.25 mm (point A) when the first blister, for example the weakest, in this case the blister 29 of FIG. 7, is actuated.

La déformation du cloquant a pour conséquence que l'effort diminue bien que la course de la touche de commande augmente jusqu'à 1,4 N environ. Le creux E correspond à un premier contact électrique réalisé par le premier cloquant. Puis l'effort se poursuit jusqu'au point B qui correspond à l'actionnement du cloquant le plus dur, en l'occurrence le cloquant 23 de la figure 7, ce qui correspond à une course totale de la touche de commande 1, de l'ordre de 1,85 mm. La déformation du cloquant 23 correspond à une diminution de l'effort après le point B. Le creux F correspond à un deuxième contact électrique réalisé par le deuxième cloquant. Si l'on continue à exercer un effort sur la touche de commande 1, il se produit une très faible course supplémentaire ou surcourse car on arrive pratiquement en butée. L'effet différentiel correspond à la différence d'effort entre les points B et A du diagramme, cet effet différentiel étant déterminé par l'écart X entre les axes 13 et 13′ du palonnier. Cet effet différentiel permet d'obtenir un effet tactile double encore appelé point dur.The deformation of the blister means that the force decreases although the stroke of the control button increases up to approximately 1.4 N. The hollow E corresponds to a first electrical contact made by the first blister. Then the effort continues until point B which corresponds to the actuation of the hardest blister, in this case the blister 23 of FIG. 7, which corresponds to a total stroke of the control button 1, of around 1.85mm. The deformation of the blister 23 corresponds to a reduction in the force after point B. The hollow F corresponds to a second electrical contact made by the second blister. If one continues to exert a force on the control button 1, there is a very small additional stroke or overtravel because one arrives practically in abutment. The differential effect corresponds to the difference in force between points B and A of the diagram, this differential effect being determined by the difference X between the axes 13 and 13 ′ of the lifter. This differential effect makes it possible to obtain a double tactile effect also called hard point.

La courbe en pointillés D sur la figure correspond au phénomène d'hysteresis lors du retour de la touche de commande 1 à la position neutre de repos.The dotted curve D in the figure corresponds to the hysteresis phenomenon during the return of the control button 1 in neutral rest position.

La disposition des cloquants 23 et 27 en côte à côte et sensiblement dans un même plan, permet de gérer, si besoin était, deux circuits électriques complètement dissociés. En effet, on peut prévoir un premier circuit dont le commutateur serait commandé par un cloquant - fermeture au point B - et un deuxième circuit indépendant dont le commutateur serait commandé par un autre cloquant avec une fermeture au point A du diagramme de la figure 9.The arrangement of the blisters 23 and 27 side by side and substantially in the same plane, makes it possible to manage, if necessary, two completely dissociated electrical circuits. Indeed, a first circuit can be provided, the switch of which would be controlled by a blister - closing at point B - and a second independent circuit, the switch of which would be controlled by another blister with a closure at point A in the diagram in FIG. 9.

Le diagramme de la figure 9 est donné à titre approximatif car dans la réalité, il y a lieu de tenir compte des tolérances de fabrication, des jeux qui peuvent exister entre les différentes pièces et de la nature de la lame souple de rappel.The diagram in FIG. 9 is given as an approximation because in reality, it is necessary to take account of manufacturing tolerances, the clearances which may exist between the different parts and the nature of the flexible return blade.

Dans tout ce qui précède, on a fait référence à un seul circuit imprimé capable de commmuter aussi bien les courants faibles que les courants forts. Bien évidemment, on peut adopter la structure telle que celle décrite dans le brevet No 86 13 740 qui est incorporée dans la présente description pour ce qui concerne les circuits électriques disposés l'un au-dessus de l'autre et les caractéristiques communes du boîtier 4. Les deux circuits qui sont parallèles et reliés entre eux permettent de constituer un commutateur à électronique intégrée relié directement à la charge à commander sans nécessiter de boîtier d'interface.In all of the above, reference has been made to a single printed circuit capable of switching both low and high currents. Obviously, it is possible to adopt the structure such as that described in patent No 86 13 740 which is incorporated in the present description as regards the electrical circuits arranged one above the other and the common characteristics of the housing. 4. The two circuits which are parallel and connected together make it possible to constitute a switch with integrated electronics connected directly to the load to be controlled without requiring an interface box.
