PURPOSE:To enable a device to be operated with a single specification even if many kinds of load control systems are available, by selecting any control system with a mode change-over switch. CONSTITUTION:A plurality of kinds of switching control programs for an electromagnetic contactor 5 according to the working state of respective press-button switches 21, 22, 24, 25 and a mode change-over switch 26 are stored in a control circuit 28, and based on the input state of an input circuit 23 and identification signal Sd or the like from an action discriminating circuit 20, necessary ones among a plurality of the switching control programs are to be run selectively. By the control circuit 28, an output contact 29 is switching-controlled. Accordingly, by the output of the control circuit 28, the make and break of the electromagnetic contactor 5 according to the electrical conduction or interruption of an exciting coil 5a and the state and stop of a motor 1 can be controlled. |
