Wiring method of tripod rocker switch

The structure of the three-leg rocker switch is shown in the figure, the middle leg is the elastic common point, one on both sides is the NC (normally closed) point, and the other is the NO (normally open) point.

One is the zero line, and the mark is N. One is the line of lights, generally marked as L. One is the line of fire to the lights.


The three pins are one fire, one zero, and one control. Use a multimeter to measure the resistance. When the switch is activated, the resistance of the two inner legs is zero capacitance is the control pin and the live wire. When the switch does not move, there is a certain resistance is the live wire And the zero pin, the zero pin and the control pin have infinite resistance. The rocker switch is also called the wave switch, and its structure is the same as the toggle switch, except that the button handle is replaced with a ship shape.




he boat-shaped switch part has a metal sheet with a spring fulcrum in the middle. The spring displacement and the aging and deformation of the plastic bracket make the switch inflexible. You can disassemble it after the power is turned off and have a look. If the plastic part is not damaged, it may be restored. The neutral wire inside the switch is straight-through, which has nothing to do with the switch components. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral wire of the switch is damaged. You can cut off the damaged section and reconnect the wiring. Pay attention to the insulation to ensure . It is also possible that the indicator pin has a short circuit, just re-wiring.
