how does a motor centrifugal switch work
A centrifugal switch solves a problem inherent in single-phase AC electric motors: By themselves, they don't develop enough torque to begin turning from a dead stop. The centrifugal switch turns on a circuit, providing the needed boost to start the motor.hen you turn the motor on, the switch conducts electricity to a capacitor and an extra coil winding in the motor, increasing its starting torque. As the motor's revolutions per minute increase, the switch opens, as the motor no longer needs the boost.
