Customized Tactile Metal Dome Flat Membrane Switch, Membrane Switch Keypad LCD Window
Membrane switches typically feature three discreet layers; the top layer, commonly referred to as the graphic overlay, directs the user to the functionality beneath by way of printed graphics. The next layer contains the printed circuit, including the domes and embedded electronics of the membrane switch, as well as the flat flexible tail and specified connector. Finally, the bottom layer is usually made of a pressure-sensitive adhesive with a removable liner; the customer typically installs the finished membrane switch on their device before final assembly and test. Membrane Switch and Panel has worked with a range of different industries manufacturing the ideal membrane switch for our customer’s unique needs and specifications. If you feel a membrane switch solution would be appropriate for your user interface, contact us today to assist in the production of the best membrane switch for your specific application.
