。In series with the motor circuit, when the output shaft of the actuator reaches a predetermined position or a predetermined load is applied to the output shaft, the switching contact is switched from a normally closed contact to a normally open contact to stop the motor, and then reverse rotation. In the operating circuit of an actuator, which is formed by inserting a limit switch capable of passing a current in one direction, a diode with one side of the switching contact serving as an anode is inserted between the switching contact piece and the normally closed contact of the limit switch. An actuator operating circuit characterized by:
