What Is a Centrifugal Switch?

Single-phase motors are installed on the motor rotor and the circuit is connected in series in the starting circuit. The switch is turned on when the rotor is stationary, and turned off when a certain speed is reached. The centrifugal switch is mainly used to control the starting coil of a single-phase motor.
