Membrane Switches: A membrane switch is an electrical switch for turning on and off a circuit. It differs from a mechanical switch, which is usually made of copper and plastic parts: a membrane switch is a circuit printed on a PET or PC. The ink used for silk screening printing is usually copper / silver / graphite filled and therefore conductive. Membrane switches typically serve as the tactile interface for machines, devices and electronics.
