In the following, explaining the switching device and this hair of an embodiment according to the present invention in detail with reference to attached drawing The load control system of a bright involved embodiment.In addition, in the following description, it is negative to instantiate illumination as load It carries, but the type loaded is not limited to lighting load.
As shown in fig. 6, the load control system of present embodiment have switching device 1 and three banked relays 2 (2A, 2B、2C).Wherein, in the following description, the mark of " 2A ", " 2B ", " 2C " are marked in the case where distinguishing three banked relays Note marks the label of " 2 " in the case where not differentiating between three banked relays.Similarly, in the feelings for distinguishing three lighting loads The label that " 4A ", " 4B ", " 4C " are marked under condition, the label of " 4 " is marked in the case where not differentiating between three lighting loads.
Banked relay 2 be it is previous known, by main contacts 20, relay coil 21, auxiliary contact 22, diode 23, 24, the compositions such as a pair of of signal terminal (the first signal terminal 251, second signal terminal 252).Main contacts 20 be inserted into for from Power supply (AC power 3) power to lighting load 4 for circuit.The public affairs of auxiliary contact 22 are connected in one end of relay coil 21 Terminal altogether.In addition, the other end of relay coil 21 is connect with the first signal terminal 251.
The anode of the switched terminal connection diode 23 of one side of auxiliary contact 22, the switching of another party of auxiliary contact 22 Terminal connects the cathode of diode 24.Auxiliary contact 22 are configured to interlock with main contacts 20, are opened for example, being in main contacts 20 The public terminal of auxiliary contact 22 is connect with the switched terminal of 23 side of diode when state (with reference to Fig. 6), is in main contacts 20 The public terminal of auxiliary contact 22 is connect with the switched terminal of 24 side of diode when closed state.In addition, the cathode of diode 23 And the anode of diode 24 is connect with second signal terminal 252.In addition, though the illustration is omitted, but in the diode of a side Series circuit (differential circuit) inserted with capacitor and resistance between 23 anode-cathode.
When applying DC voltage between signal terminal (that is, when so that the first signal terminal 251 compared to the Binary signal terminal 252 applies DC voltage between the first signal terminal of mode pair 251 and second signal terminal 252 of high potential When), exciting current (electric current of first direction) is with first 251 → relay coil of signal terminal, 21 → auxiliary contact, 22 → bis- pole The path of 23 → second signal of pipe terminal 252 is flowed, therefore main contacts 20 is switched to closed state (namely from opening state It says, main contacts 20 becomes connecting).When main contacts 20 is connected, with linkedly (the i.e. auxiliary contact 22 of auxiliary contact 22 of main contacts 20 Public terminal) be switched to 24 side of diode, therefore there is no the exciting current (electricity of first direction in relay coil 21 Stream) flowing.In this way, when the electric current of first direction (from the first signal terminal 251 to the direction of second signal terminal 252) is in a pair When being flowed between signal terminal 251,252, banked relay 2 becomes closed state, and a pair of of signal terminal from opening state 251, there is no the electric current flowings of first direction between 252.But since banked relay 2 is the self-locking type for having permanent magnet Relay, therefore even if exciting current (electric current of first direction) stopping after main contacts 20 maintain closed state.
