Membrane Switch Manufacturing and Supply

Membrane switches are used  in consumer and industrial applications requiring a input pad device. Membrane switches are low cost, considered reliable, and are available in custom or off-the-shelf configurations. By fabrication several layers of polyester (PET) or plastics and onto a  printable conductive electronic circuits and a graphic overlay, membrane switches offer product developers a flat keypad type interface system as opposed to classic mechanical type keypads. Membrane switch assemblies are great space and weight savings alternative to mechanical keypads.

Manufacturers and suppliers of membrane switches fabricate assemblies using flexible plastic membrane material , domed or flat mechanical type switch devices and tactile and non-tactile type switches.  Membrane switches are used within industry and products for numerical keypads, graphical keypads, keypad control panels, and membrane switch overlays.  Below, is a typical membrane switch assembly.
