Control potentiometer with external setting - has spiral groove in which contact driven by pressure element moves to change setting
DE 2635614 A1
Abstract
The potentiometer comprises a ceramic disc body (1) with a spiral or part circular resistive track (2) on one of its plane surfaces, with two end terminals (4). There is a resistive layer (3) in the resistive tract (2) and an axis symmetrical contact (6) movable on the resistive track (2), whose shape corresponds to that of the track (groove). A metal pressure element (7) applies elastic pressure to the contact (6) transmitting to it the rotational movement and connecting it to the wiper terminal (5). There is a device (9) through which the rotational movement is applied to the pressure element (7); and a metal element (11) applying pressure to the pressure element (7) and supporting the wiper terminal (5).
