The lines are arranged separately, but the switch wiring is wrong (to merge together), then just adjust the switch wiring (the zero line can be shared, and the two electrical appliances are in parallel state); 2.Originally, there was a line of "one switch controlling two electrical appliances", but because the lines were buried in the wall, they could not be rearranged. That is only in the internal circuit of the exhaust fan, a pull switch is inserted into the power inlet line, and the pull switch controls the exhaust fan.
The result of this arrangement is that the lights can be turned on without the exhaust fan, but the exhaust fan must be turned on.

Disassemble the switch to connect the light and see how many wires there are, if there are only two, it means that the wire of the exhaust fan and the wire of the lamp are connected together. There is no other way but to re-run the line from the line pipe. If there are four wires, determine which two are connected to the fan, and then change them to the other switch.
Bathroom exhaust.
The value of the BAI fan is relatively low, and generally speaking, if the exhaust fan has been used for more than 3 years, the DAO does not need to enter again. >>>More
This is the reason why the exhaust fan and the bathroom light in your home are connected in series, and the voltage required for the motor of the exhaust fan is large when it starts, and the voltage required will be less after starting, and the light will flash a little.
It is best for the exhaust fan to have convection air, this kind of thing is worth what you pay for (of course, excluding being cheated) It is best to press two and two exhaust ports for dry and wet separation, and finally all belong to one exhaust fan. If the bathroom.
Buy at least an 8-inch exhaust fan, and the 8-inch ventilation fan refers to an 8-inch fan. 1 inch = millimeter, = centimeter. >>>More
