Membrane Switch Backlighting

Differentiate Your Products with Fiber Optic Backlighting

Innovative and Inspired Lighting Solutions That Adapt to Your Membrane Switches & Keypads

Fiber optic lighting for membrane switches offer many benefits over other lighting solutions such as Electroluminence (EL) or using discrete LEDs. Fiber optics have longer life than EL. It also allows you to uniformily illuminate a larger area with fewer LEDs. They are more durable and well suited for rugged applications.

Optical fibers offer many other unique benefits:


As thin as 0.2 mm for superior tactile response


Bright, Efficent, Low Power


Easy to protoype, Low-Cost, No tooling required
