As shown in Figure 6, the load control system of present embodiment has switching device 1 and three banked relays 2 (2A, 2B, 2C).Wherein, in the following description, marking the mark of " 2A ", " 2B ", " 2C " when differentiation three banked relays, marking the mark of " 2 " when not distinguishing three banked relays.Similarly, marking the mark of " 4A ", " 4B ", " 4C " when differentiation three lighting loads, marking the mark of " 4 " when not distinguishing three lighting loads.
Banked relay 2 is in the past known, by main contacts 20, relay coil 21, auxiliary contact 22, diode 23,24, a pair signal terminal (the first signal terminal 251, secondary signal terminal 252) etc. form.Main contacts 20 is inserted into and supplies circuit for what power from power supply (AC power 3) to lighting load 4.The public terminal of auxiliary contact 22 is connected in one end of relay coil 21.In addition, the other end of relay coil 21 is connected with the first signal terminal 251.
The switched terminal of one side of auxiliary contact 22 connects the anode of diode 23, and the switched terminal of the opposing party of auxiliary contact 22 connects the negative electrode of diode 24.Auxiliary contact 22 are configured to and main contacts 20 interlock, such as, when main contacts 20 is in open mode (with reference to Fig. 6), the public terminal of auxiliary contact 22 is connected with the switched terminal of diode 23 side, and when main contacts 20 is in closure state, the public terminal of auxiliary contact 22 is connected with the switched terminal of diode 24 side.In addition, the negative electrode of diode 23 and the anode of diode 24 are connected with secondary signal terminal 252.In addition, although the diagram of eliminating, between the anode-cathode of the diode 23 of a side, be inserted with the series circuit (differential circuit) of capacitor and resistance.
