Manufacturing for Custom Membrane Switches & Keyboards

Elite Sales & Technology, LTD is an industry leader in the production of custom membrane switches used widely in medical, automotive, and electronics applications. Each custom membrane switch has a basic 3-layer construction that consists of a top polyester layer with printed graphics and conductive pads underneath. The second layer is a polyester film spacer with switch cutouts, while the third layer could be a film with the switch contacts printed in conductive ink, a printed circuit board or membrane keyboard with the switch contact etched in. More complex layering can be utilized as well.

Our engineers will work with you to design a custom membrane switch or membrane keyboard with the mechanical and electrical specifications appropriate for its operating environment and with the graphical look you desire. A custom membrane switch can incorporate material, films, and other components to meet specific requirements such as backlighting, tamper protection and insulation. Tactile switches can be created for your membrane keyboard by adding embossing to the top layer, or by adding metal domes to the bottom layer. We produce prototype samples for customer approval and are capable of any size production run with short lead times.

Elite also designs flex-circuit interconnect assemblies, similar to custom membrane switches without the graphic overlay, and maintains four electronic manufacturing services (EMS) assembly lines to provide complete, start-to-finish production.
