PURPOSE:To execute batch operation of on-and-off operation of each separate load and a prescribed load on one place by providing a logical controlling circuit for applying an external control signal to a slave device corresponding to the prescribed load from a set state and a load state of a load control selecting part at operation of a batch operating switch. CONSTITUTION:Each slave device 91- connects full-wave rectifiers 101- in parallel to separate operating switches SW1-, and is connected to on-off control parts 111- having function an on-off state discriminating circuit 8, and also a switching function for turning on and off the output terminals of full-wave rectifiers 101- in accordance with an external control signal, between the output terminals of the full-wave rectifiers 101-. A logical controlling circuit 12 sends out an external control signal of one or off to the on-off controlparts 111- of the corresponding slave devices 91 in advance in accordance with the opera tion of batch operating switches SWa, SWb and SWc, and in case of a batch operation, the logical controlling circuit 12 detects a state of each load 11- by the inputs from the on-off control parts 111-; and a set state of a load control selecting part 13, the corresponding load 11- are turned on or off from the resulted state. |
