How can an electric fan be wired without a switch?

Wiring diagram of electric fan without switch is as follows:

1. First, connect the two wires of the power cord to the two power connectors of the electric fan. Generally speaking, the red line of the power cord is connected to the positive pole of the electric fan, and the black line is connected to the negative pole of the electric fan.

2. Next, connect the two ends of the capacitor to the two power interfaces of the electric fan. Note that the two terminals of the capacitor cannot be connected reversely. Generally speaking, the anode of the capacitor is connected to the anode of the electric fan, and the cathode is connected to the cathode of the electric fan.

3. Finally, connect the two terminals of the resistor to the two power interfaces of the electric fan respectively, and pay attention to the fact that the two terminals of the resistor cannot be connected backwards. Generally speaking, the anode of the resistor is connected to the anode of the electric fan, and the cathode is connected to the cathode of the electric fan.

After the wiring is completed, insert the power plug into the socket and the electric fan can work normally. Since there is no switch, it will run all the time as long as it is plugged in, and the only way to stop running is to unplug it.
