Drawing

The role of the ground pin

The longer of the three legs is grounded and can be called the ground pin, and the other two shorter legs are used to connect household appliances to the circuit, so they can be called conductive pins. If the metal shell of the household appliance is charged due to the damage of the insulator or other reasons, the ground pin will form a ground short-circuit current, so that the metal shell of the household appliance is grounded and discharged to the ground, so that people will not be electric shocked and play a role of safety protection.

The difference between tact switch and push button switch

1) Tact switch is a kind of click switch, that is to say, press to turn on and release to turn off. Simply put, it is to tap the switch that turns on instantly.

2) The push button switch refers to the  switch that is pressed to turn on. In fact, some people call the tact switch also the push button switch. The push button switch usually means that a switch with a larger stroke can be self-locking and non-locking, highlighting the force of a press. The tact switch means short stroke, short contact, and light touch.
