The boat-shaped switch, the kind of red light that is very common when it is turned on. Sometimes it can't be turned off, just can't bounce back, and often the fault of the air switch is jumped, the way to deal with the fault:

There is a metal sheet inside the boat-shaped switch, with a spring fulcrum in the middle, spring displacement and aging deformation of the plastic bracket, the switch is not flexible, and can be disassembled after power off to see if it is not damaged by plastic parts, it may be able to recover. The neutral line inside the switch is straight through and has nothing to do with the switch parts. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral line of the switch is damaged. The damaged section can be cut off from the scratch and the insulation must be ensured. . It may also be that there is a short circuit in the foot of the indicator, just connect from the beginning.

The difference between two feet and three feet

 The rocker switch is also called a rocker switch. Its wiring pins have two terminals and three terminals. The following Huaqin editor takes you to understand the difference between the rocker switch and the two and three legs of the rocker switch:

1. The two-legged rocker switch and rocker switch rocker switch are the same as the usual switch, which has the effect of opening and closing the circuit. Never allow his two terminals to be connected to the positive pole and the negative pole, as this will short-circuit.

The accurate connection method is that the positive pole of the power supply can enter any terminal of the boat switch, and then its other terminal leads out to the load and then returns to the negative pole of the power supply.

2. The three terminals of the three-leg boat switch and rocker switch should not have indicator lights, but with normally open and normally closed points, usually the center is the common point, and the two ends are normally open or normally closed (ie different Azimuth switch) When the switch is used, the center is the moving contact, and the two ends are the fixed contacts; when making a single switch, you can only connect the center column and any one of the sides.
