Abstract
PURPOSE: To eliminate the need for providing turnabout contactors with capacity that interrupts currents, by interrupting the currents of a motor circuit by means of a bypass contactor by opening the turnabout contactors so that it continually be delayed more than the bypass contactor.
CONSTITUTION: When an operation switch 9 parts from a location F or a location R, the time delay of a bypass control circuit 10 becomes unconcerned because the excitation of operation coils 4', 5' and an operation coil 8' is simultaneously intercepted by means of the operation switch 9 before the bypass control circuit 10 interrupts the excitation of the operation coil 8'. Thus, the currents of a motor circuit are surely intercepted by means of the bypass contactor 8' if the opening delay time of the bypass contactor 8' is beforehand shortened only by a bit to the opening delay time of turnabout contactors 4, 5.
