Illuminated keyboards

Illuminated keyboards are designed using a backlight feature to provide visibility under low light conditions also known as backlit keyboards. The illumination is achieved by using LED light under the switches. The illuminated portion of a switch is made up of translucent semi-transparent material to allow the light to pass through. Illuminated Keyboards are also made by using snap domes, or push buttons, where the LED is inbuilt in the switch itself.

These backlit keyboards can be used in standard membrane switch, PCB based membrane switch and capacitive touch membrane switch. They are also used in systems where it is necessary to highlight the functions in operation by illuminating the respective switches.
