What are Membrane Switch?

A membrane switch is a momentary switching device that is manufactured by using a series of flexible layers of polymer films and adhensives. The upper-most layer, called a graphic overlay, is manufactured by printing on the second surface of clear polyester or polycarbonate film. It is a circuit printed on PET, PC film / sheet. The ink used for screen printing is usually copper / silver / graphite filled and therefore conductive.In between is a die-cut spacer that maintains an open circuit, where a finger press establishes contact switching it on.Membrane switches, when combined with components such as a tactile dome, graphic overlay, or integrated LEDs or resistors can provide the designer with virtually limitless capablities to create the ideal custom user interface for their products.
