Ceiling Fan 4 Wire Switch

A ceiling fan 4 wire switch is a type of electrical switch that is used to control the operation of a ceiling fan. It has four terminals, which are used to connect the switch to the fan's power supply, the fan's motor, and the fan's light fixture. The switch is typically mounted on the wall near the fan, and it is used to turn the fan on and off, as well as to adjust the fan's speed and light settings.

The four terminals on a ceiling fan 4 wire switch are typically labeled as follows:

Line (L): This terminal is connected to the power supply.
Load (L1): This terminal is connected to the fan's motor.
Neutral (N): This terminal is connected to the neutral wire in the power supply.
Ground (G): This terminal is connected to the ground wire in the power supply.

To wire a ceiling fan 4 wire switch, the following steps should be followed:

Turn off the power to the circuit that will be used to power the fan.
Connect the black wire from the power supply to the Line terminal on the switch.
Connect the white wire from the power supply to the Neutral terminal on the switch.
Connect the green or bare copper wire from the power supply to the Ground terminal on the switch.
Connect the black wire from the fan's motor to the Load terminal on the switch.
Connect the white wire from the fan's motor to the Neutral terminal on the switch.
Connect the black wire from the fan's light fixture to the Light terminal on the switch.
Connect the white wire from the fan's light fixture to the Neutral terminal on the switch.
Turn on the power to the circuit and test the switch to ensure that it is working properly.

Ceiling fan 4 wire switches are a versatile and convenient way to control the operation of a ceiling fan. They are easy to install and can be used with a variety of different types of fans. If you are planning to install a ceiling fan, be sure to choose a switch that is compatible with the fan and that meets your specific needs.
