As described above, according to the present invention, the output of the detection means that detects the on/off state of the power switch that opens and closes the power supply line of the vehicle, and the output of the electrical component switch that controls the on/off of electrical components. The logical operation is performed, the signal obtained as a result of this operation is transmitted via the multiplex transmission means, and the electrical components are driven based on this transmitted signal, so that it is possible to use a large power supply line. The number of wires can be reduced to one, and therefore the weight of the wire harness can be reduced, the diameter can be reduced, and the wiring can be simplified.
