Abstract:
Example of backlit switches are described. In an example, a backlit switch includes a printed circuit board (PCB) and a dome-type button coupled to the PCB. The dome-type button has a light transmitting portion. A light source is mounted on a first side of the PCB, and a tact switch is mounted on a second side of the PCB that is opposite to the first side. Further, a projection is provided to trigger the tact switch, in response to pressing of the dome-type button.
