KEYLOCK PUSH BUTTON


Working Principle

This kind of switch controls the switching state of the circuit through the insertion and rotation of the key, based on the mechanical and electrical principles :

   When the key is inserted into the switch hole, its shape and length matches the lock core inside the switch to allow the lock core to rotate, the rotation of which will drive the contact piece inside the switch and thus change the connection state of the circuit.


   Conclusion: 

When the key is not inserted, the switch is in the off state and the circuit is not working ; When the key is inserted, the lock core is connected to the contact piece and then the circuit is energized. At the same time, as long as you turn the key, you can control the switching state of the circuit. When the key is rotated to the maximum angle, the contact piece will be disconnected from the lock core, then the circuit is powered off, and the switch is in the off state in the end.


Advantages

It only needs to control the switching state of the circuit through the insertion and rotation of the key, without any required additional power supply. And this kind of switch can also prevent others from illegal operation and protect the safety of the circuit.
