Schematic diagram of ceiling fan switch connection

Wiring diagram of ceiling fan speed regulating switch is as follows:

1, the common three-wire connection mode of governor (black, red and blue) = zero line, live line and bottom line. This connection is the simplest.

2. Measure the resistance with a universal pen. Set aside the two with the largest mutual resistance among the three, and measure the resistance of the remaining one (usually red) and the other two respectively. Connect one end of the capacitor with large resistance (usually blue) to the zero line and the other end to the zero line, and connect the capacitor with small resistance (usually black) to the zero line. The governor is usually connected in series on the live wire.

3. Classic connection mode: the live wire (neon light will light up when using the electric pen) is connected to the L end of the governor, the other end of the governor is connected to the ceiling fan, and the other end of the ceiling fan is connected to the zero line (neon light will not light up when using the electric pen), so that the connection between the ceiling fan and the governor is completed.

4. The motor terminal position N is connected to the zero line first, and there are 123 points on L, which are the control line of the electric fan, and the 0 in the governor is connected to the fire line. In fact, the line of control is also the line of fire. We can understand that there is a governor in the middle of this fire line, and the role of this governor is only to control the opening and closing of the fire line.
