Back Lit Membrane Switches

CSI Keyboards Inc. is the back lighting specialist in the Membrane Switch industry. We have designed elaborate backlit membrane switches and signage for military, medical, and industrial applications with each having very diverse parameters and needs. We recently tackled a project for the Navy that our competitors were unable to quote, let alone produce. After working with the Navy on their concept and needs, CSI Keyboards successfully designed and produced the backlight membrane switch unit meeting all of the parameters laid out by the naval engineers and designers. We are experts at utilizing LED's for back lighting of membrane switches as well as the more expensive and design limiting technologies such as Electro Luminescence and Fiber Optics.
