A membrane switch is a low power electrical switch, comprised of silver or graphite impregnated ink, printed and cure bonded to a plastic substrate – polyester being the most common – and assembled with various adhesive layers and finished with a graphic overlay. Major benefits in designing a membrane switch into your product include ease of cleaning, environmental sealing, low profile, and the ability to create a visually attractive interface.
