Waterproof Metal Dome Membrane Switch / Thin Shape Membrane Panel Switch
Metal Dome Membrane Switch Introduction
Metal Dome Membrane Switch is an electrical switch for turning a circuit on and off. It differs from a mechanical switch, which is usually made of copper and plastic parts: a membrane switch is a circuit printed on PET or ITO. The ink used for screen printing is usually copper / silver / graphite filled and therefore conductive
