Membrane Switches

Membrane Switches are, as the name suggests, ultra thin electrical devices for use in low voltage control applications. Put simply an electrical circuit is printed, using conventional techniques, on to a pair of clear membranes which, when pressed together, form a make/break switch. This 'filling' is sandwiched between a base substrate for mounting the device on equipment and a Graphic Overlay which forms the user interface with its symbols and control areas - finger-pads if you like. Because there are no conventional moving parts these neat little devices are robust and reliable over many millions of operations. The connection between the Membrane Switch and the equipment controlled is by an Industry Standard ribbon with conductors at .1 inch pitch.
