Working principle of rocker switch

Rocker switch, also called rocker switch, is a kind of control device commonly used in household appliances to control power supply. Next, I will talk about the working principle of the rocker switch with indicator light.

The red light is very common when it is connected. Sometimes it can't be turned off, it just can't bounce back, and it often trips the switch. Troubleshooting method: There is a metal sheet inside the rocker switch, and there is 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 power off to have a look. If the plastic part is not damaged, it may be ok. recover.


The neutral line 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 line passing through the switch is damaged. You can cut off the damaged section and re-wire it. Pay attention to the insulation. . It may also be that the pin of the indicator light is short-circuited, just re-wire it.

Technical parameters 1. Rated working voltage and current Rating 3A/6A/15A 250V2. Operating temperature range Temperature -25+85 ℃3. Contact Resistance <0.03Ω4. Actuating Force 1.3+0.5N5. Insulation Resistance >100MΩ6. Life (switching Life) 10000 times.

The test method of the life of the rocker switch mainly tests the number of opening and closing until it is damaged.


If you don't need to manually use a small motor to drive the eccentric opening and closing switch, use a counter to record the number of times. This switch requires safety certification. If the product is sold domestically, use CQC. If the product is sold abroad, it depends on which country it is sold to, such as UL in the United States, CUL in Canada, and safety certification such as VDE, ENEC, and TUV in European countries.

Rocker switches are used in water dispensers, treadmills, computer speakers, battery cars, motorcycles, ion TVs, coffee pots, power strips, massage machines, etc., mainly for household appliances and the like.
