The rocker switch is also called the rocker switch. Its wiring pins have two terminals and three terminals. The following Hongju switch will show you the difference between rocker switches, two-legged rocker and three-legged rocker switch:
1. Two-leg rocker switch, rocker switch
The rocker switch is the same as a general switch, which functions to open and close the circuit. It is never allowed to connect his two terminals to the positive pole and the negative pole, otherwise it will short-circuit.
The correct connection method is that the positive pole of the power supply can enter any terminal of the rocker switch, and then its other terminal will lead to the load and then return to the negative pole of the power supply.
2. Three-legged rocker switch, rocker switch
The three binding posts should not have indicator lights, but with normally open and normally closed points. Generally, the middle point is the common point, and the two sides are normally open or normally closed (switches in different positions)
When making a transfer switch, the middle one is a moving contact, and the two sides are fixed contacts; when making a single switch, you can only connect to the middle post and any one of the sides.
