Anonymous users2024-01-23This problem is rare, the four-open switch will generally not have a problem, I don't know how much power your headlights have, if the current is too large, the switch is not in good contact, ignition, and the voltage is too low. There is also whether the wire is too thin and too long, resulting in insufficient voltage. If you suspect that the switch is problematic, you can try an external air switch.
Then check whether the voltage 220V is normal.
If the problem cannot be ruled out, the specific situation of the lamp and switch circuit will be explained in detail before it is solved.

Anonymous users2024-01-20As long as the switch and light control are normal, there is no problem, the key is, what type of lamp.
It should be said that there are four wires in the control box on the wall, right? If that's the case, then here's why: >>>More
Just connect it according to the circuit diagram provided by the bath bomb; The original line of the bath bomb can be removed, and six wires can be placed from the bath bomb installation position to the switch installation position (if conditions permit, the color of the line can be selected white, green, red, yellow and other two-color lines, and the other two-color line is only used with one, and the other is spare) white, green, red, yellow line one end is connected to the port of the corresponding color of the bath bomb, one other color line L terminal, the other end of the white line is connected to the lighting switch, the green line, the red line is connected to the two heating switches, and the yellow wire is connected to the ventilation switch, On the terminal of the L terminal, there is a wire on the connector; The live wire of the power supply is connected to the L terminal of the bath bomb, and the neutral wire is connected to the N terminal of the bath bomb. If possible, for safety, connect a leakage switch on the power supply.
The reason for connecting the four wires is that one wire is the power cord and the other three wires go up to the lamp head. In other words, the three heads use the same power cord, and the power supply is sent to each of the three heads through the switch, so you will see that there are four wires. >>>More
If you don't know, I don't know if it's a control line or a ground line, and if it's a zero line in blue, I can't tell.
If the warm white light is only as bright as a star, or if there is a warm light that is not bright, it is recommended to change the light source and driver.
