The boat type switch is also called the wave switch. Its structure is the same as that of the button switch, except that the button handle is replaced by a boat type. The rocker switch is often used as a power switch for electronic equipment. Its contacts are divided into single-pole single-throw and double-pole double-throw, and some switches also have indicator lights. Next, I will explain in detail how to repair the broken ship-type switch and the internal structure diagram of the ship-type switch.

How to repair the broken ship switch

Common faults of the rocker switch: the rocker switch, the red light is very common when it is turned on. Sometimes it can’t be turned off, it just can’t bounce back, and it often jumps the fault of the air switch.

Troubleshooting method: There is a metal sheet inside the rocker switch with a spring fulcrum in the middle. The spring displacement and the aging deformation of the plastic bracket make the switch inflexible. You can take it apart after the power is turned off. recover. The neutral wire inside the switch is straight through and has nothing to do with the switch components. Therefore, if the switch trips the air switch, the insulation layer of the neutral wire passing through the switch is damaged. The damaged section can be cut off and rewired. Pay attention to ensure the insulation. . It may also be that there is a short circuit at the foot of the indicator light, and you can rewire it.

The outer silver terminal is normally open, the middle is the common terminal, and the gold terminal is connected to the indicator light.

The three feet are one fire, one zero and one control. Use the multimeter resistance gear to measure it. When the Yingxin electronic switch is active, the resistance of the two feet is zero. The live wire and the zero wire, the zero wire and the control foot have infinite resistance. The boat type switch is also called the wave switch. Its structure is the same as that of the button switch, except that the button handle is replaced by a boat type.

One is the zero line, marked N. One is the live wire of the incoming light, generally marked as L. One is the live wire to the lights. The live line of the incoming light is connected to L of the switch, and the neutral line of the incoming light is connected to N. The two lines of the lamp, one is connected to the other empty pin of the rocker switch, and the other is connected to the neutral line N. It is not a normally open and normally closed switch. It has only one set of switches on and off, one of which is the light lead on the side, which is connected to the other power supply. The connection method is that the two ends are connected to 220 volts, and the load to be controlled in the middle.
