Membrane-switches serve as a way of giving an operator interface distinctive graphics or an attractive look. The overlay or top layer of the switch is screen-printed with graphics (usually on the back of the overlay for protection from the environment). Typical overlay materials include polyester and polycarbonate and may have a thickness ranging from 0.005 to 0.015 in.

The typical circuit material for membrane keypads is silver conductive ink screen printed on a polyester substrate. The circuit layer is die cut to the right shape after printing. Alternatively, copper-etched layers or a conventional PCB can also serve as the base circuit.
