PURPOSE:To simplify the wiring structure by providing a controller for controlling a power switch and indicator groups on the basis of the indicator group for indicating the control switch group for generating a control signal and the operating state and the control signal. CONSTITUTION:Control switch group 40 is composed of normal rotation switch 22, a reverse switch 24 and a stop switch 26, and indicator group 42 is composed of a normal rotation indicator lamp 32, a reverse indicator lamp 34, a stop indicator lamp 36 and a defect indicator lamp 38. A controller 44 inputs a control signal from switches 22-26 of any of the group 42, and controls electromagnetic switches 14, 16 and the lamps 32-38 of the group 42 by logically judging the control commands such as normal/reverse drive and stop of a motor 10 on the basis of the control signal. |
