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 and a hemispherically shaped rubber actuator. The operator applies pressure to the pedal thereby depressing the actuator and initiating operation of the equipment. The pedal 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.
