Membrane Switches

What is a Membrane Switch?

A membrane switch is basically a wafer thin, self-contained, printed keyboard. They can be multi-layered. Standard three-layer components consisting of a clear polyester (PET) film on top with the graphics and conductive pads printed under the surface. The middle layer is a polyester film which acts as a spacer with cut outs for the switch areas. On the bottom, there is either another polyester film with the switch contacts and interconnections printed in conductive ink on the top surface, or a printed circuit board with the switch contact and interconnections etched into it. Contact is made by manually pressing the top layer against the bottom layer.
