Integral LEDS
We can be built with surface mount LEDs embedded into the switch package to provide a cost effective way for backlighting.
1) Embossed LED Window
This construction provides for a 180 view angle because the LED sits inside an embossed window. This also allows for a thinner construction.
2) Flat Overlay
This construction provides for a flat LED window. Filler is required to make up the height of the LED and this leads to a thicker construction.
