Abstract
PURPOSE: To detect easily an operating condition of switches and thus to simplify electrical wiring by a system wherein a resonance element is inserted in each switch in series, a frequency is assigned to each switch, which is connected with a common wire.
CONSTITUTION: Switch blocks 13, 14 are connected to an active junction box 20 through connectors 11, 12. In this case, resonance elements A0WAn are connected in series to switches S0WSn respectively, and the set of switch and resonance element is all connected in parallel. The box 20 is provided inside with a current detection circuit 21, a sweep oscillator 22, a circuit 23 to obtain a binary current value, a shift resistor 24, a storage circuit and a load driving circuit 25. An operating condition of the switches is then detected by giving a signal sweeping a timing frequency between wire couples connected in parallel and supervising a current flowing in the wire couples, and corresponding loads L0WLn are driven through the driving circuit 25.
