ABSTRACT:
A motor controlling switch device in which, when the motor is stopped in locking manner, an operating member for operating the switch and for applying current to the motor is returned from an operating position to an original position. The magnetic force of a voltage coil holding the operating member at the operating position is cancelled out by a magnetic force of a current coil which is induced therein by the locking current of the motor.
