 A membrane switch is made up of layers of plastic sheet, usually polyester. The layers are processed in such a way as to allow circuits to be made when the switch is pressed.

The top layer is a graphic overlay and makes the face of the product. Underneath the Graphic layer is a spacer layer which has holes cut into it to allow the switch to actuate and complete the circuit which is on the third layer. All the layers are bonded together with adhesive
