Key switchIn general, it means that the switch is equipped with a mechanical locking function. If you press it, the button will not jump up completely after release. If you are in a locked state, you need to press again to unlock it.

It's called a self-locking switch. The switch was used in early televisions and monitors that were completely cut off.
The difference between the self-locking light switch and the ordinary self-locking switch is merely that the self-locking light switch takes full advantage of the space in its buttons to place a small indicating light bulb or LED.

One end is connected with the zero line, and the other end is generally connected in parallel with the normally open contact of the switch through a step-down resistor. When the switch is closed, the equipment also provides power for the indicator lamp while it is running.
