Just connect the live wire to the positive pole of the switch, and the neutral wire to the negative pole of the switch, and you can use it normally.

1. Button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize circuit switching. The star connection method of phase power is to connect one end of each phase power supply or load to one point, and the other end of them is used as a lead wire, which are three phase wires of three-phase power.

2.In the electrical automatic control circuit, it is used to manually issue control signals to control contactors, relays, electromagnetic starters, etc., and the push-button switch only has two states of switch. When multiple states need to be controlled, the knob switch is used. The button switch has an automatic reset, that is, it is turned off when it is turned on, and there are self-locking, that is, it is self-locking after turning on, and it is always on. Knob switches are resettable, there are two gears that switch between on and off states, and three gears are generally used for manual, automatic, and stop switching.

3.The button switch can complete basic control such as start, stop, forward and reverse rotation, speed change and interlock. There are five terminals, one of the three contacts side by side in the middle is connected to the power supply, the other two are normally open, one is normally closed, and the other is The two terminals at both ends are the LED terminals of the button, which are connected to the power supply and the ground wire respectively.
