Abstract

A foot actuated pneumatic switch for use in association with food-equipment such as mixer-grinders. The switch includes a u-shaped compressible pedal (34) and a hemispherically shaped rubber actuator(58). The operator applies pressure to the pedal (34) thereby depressing the actuator (58) and initiating operation of the equipment. The pedal (34) operates by means of a spring-like operation which enables the pedal to return to its static position when the pressure on the pedal is removed.
