Backlighting membrane switches with fiber optics provides many benefits that cannot be obtained using standard LED backlighting or EL techniques.

Advantages:

1. Fiber optics provides a flexible and customizable back lighting layer (as thin as 0.2 mm) that can easily be incorporated between the graphic overlay and the circuit layer.

2. Can evenly backlight the entire surface area of the membrane switch.

3. Fiber optics allow for a uniform and evenly distributed backlit surface.

4. Low power consumption typically only using one single LED.
