Product Description
Capacitive Touch Membrane Switch Keyboard With Non-conductive Layer
A membrane switch consists of various layers laminated together. The layers of a basic membrane switch construction include: a membrane overlay, spacer, printer circuit, rear adhesive, and tail filler. Depending on the environment and requirements of the application into which the membrane switch plugs into, the construction can vary. For example, if shielding is necessary, a two-circuit membrane switch design would be a better construction choice.
