Embodiment
Below, the switching device and this hair of an embodiment involved in the present invention are explained referring to the drawings
The load control system of a bright involved embodiment.In addition, in the following description, it is negative exemplified with illumination as load
Carry, but the species 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, " 2A ", " 2B ", the mark of " 2C " are marked in the case where distinguishing three banked relays
Note, the mark of " 2 " is marked in the case where not differentiating between three banked relays.Similarly, the feelings of three lighting loads are being distinguished
" 4A ", " 4B ", the mark of " 4C " are marked under condition, the mark of " 4 " is marked in the case where not differentiating between three lighting loads.
Banked relay 2 be in the past it is known, by main contacts 20, relay coil 21, auxiliary contact 22, diode 23,
24th, a pair of signal terminals (the first signal terminal 251, secondary signal terminal 252) etc. are formed.Main contacts 20 be inserted into for from
The power supply road that power supply (AC power 3) is powered to lighting load 4.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 connected 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 the opposing party of auxiliary contact 22
Terminal connects the negative electrode 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 connected with the switched terminal of the side of diode 23 during state (reference picture 6), is in main contacts 20
The public terminal of auxiliary contact 22 is connected with the switched terminal of the side of diode 24 during closure state.In addition, the negative electrode of diode 23
And the anode of diode 24 is connected with secondary signal terminal 252.In addition, though diagram is eliminated, but in the diode of a side
Series circuit (differential circuit) inserted with capacitor and resistance between 23 anode-cathode.
When to applying DC voltage between signal terminal (that is, when so that the first signal terminal 251 compared to the
Binary signal terminal 252 is the mode of high potential to applying DC voltage between the first signal terminal 251 and secondary signal terminal 252
When), exciting current is with first signal terminal 251 → relay coil, 21 → auxiliary contact, 22 → diode, 23 → secondary signal end
The path flowing of son 252, therefore main contacts 20 switches to closure state (that is, main contacts 20 is changed into connecing from open mode
It is logical).When main contacts 20 is connected, linkedly auxiliary contact 22 (i.e. the public terminals of auxiliary contact 22) are switched with main contacts 20
To the side of diode 24, therefore there is no exciting current flowing in relay coil 21.But because banked relay 2 is that have
The relay of the self-locking type of permanent magnet, therefore main contacts 20 also maintains closure state after exciting current stopping.
In addition, when the DC voltage to applying opposite polarity between signal terminal (that is, when so that secondary signal
Terminal 252 is believed the first signal terminal 251 and second compared to the first signal terminal 251 for the mode of high potential (opposite polarity)
When applying DC voltage between number terminal 252), exciting current is with 24 → auxiliary contact of secondary signal 252 → diode of terminal 22
The path flowing of the signal terminal 251 of → relay coil 21 → the first, therefore main contacts 20 switches to open shape from closure state
State (that is, main contacts 20 is gone off).When main contacts 20 disconnects, linkedly auxiliary contact 22 are cut with main contacts 20
The side of diode 23 is changed to, therefore there is no exciting current flowing in relay coil 21.But stop it even in exciting current
Main contacts 20 is also maintained open state afterwards.
When banked relay 2 (main contacts 20) is connected, from AC power 3 via banked relay 2 to lighting load 4
Alternating electromotive force is supplied, so as to which lighting load 4 starts and (lighted).In addition, when banked relay 2 (main contacts 20) disconnects, no
Alternating electromotive force is supplied to lighting load 4 from AC power 3 via banked relay 2 again, lighting load 4 is closed (extinguishing).But
In the load control system of present embodiment, for each power supply road to be powered from AC power 3 to lighting load 4A, 4B, 4C
It is middle respectively with banked relay 2A, 2B, 2C dividually inserted with switch 5A, 5B, 5C.These switches 5A, 5B, 5C are, for example, in wall

2C switches to supply electric power in the short time of the time of closure state from open mode.
Also, control unit 10 is after whole banked relay 2 is connected, control polarity switching part 13 is first defeated to make
It is same potential (t=t4) to go out the lead-out terminal 133 of terminal 132 and second.In addition, control unit 10 only lights red LED, thus make
Display part 17 shows that whole lighting loads 4 is lighted.
When operation handle 110 is by carry out pressing operation in the state of being in lighting in the lighting load 4 of whole, control
Portion 10 receives operation signal from operating portion 11.Receive the control polarity switching part 13 of control unit 10 of operation signal switch to
Second lead-out terminal 133 is positive pole and the polarity (t=t5) with first lead-out terminal 132 for negative pole.Then, control unit 10 makes light
Electric three terminal bidirectional alternating-current switch coupler 14A input terminal is low level, thus to banked relay 2A signal terminal it
Between apply using the side of relay coil 21 for bear signal voltage (24 volts of DC voltages).That is, control unit 10 will be defeated
The voltage (C of reference picture 5) entered to photoelectricity three terminal bidirectional alternating-current switch coupler 14A switches to low level from high level.Thus,
Photoelectricity three terminal bidirectional alternating-current switch coupler 14A photoelectricity three terminal bidirectional alternating-current switch 141 is changed into turning on.As a result, signal is electric
Pressure (24 volts of DC voltages) is so that secondary signal terminal 252 is applied to remote control for the mode of high potential (F of reference picture 5)
Between relay 2A the first signal terminal 251 and secondary signal terminal 252 (t=t6).
In banked relay 2A, relay coil is flowed through by being applied in above-mentioned signal voltage and reverse exciting current
21, therefore main contacts 20 disconnects and auxiliary contact 22 (i.e. the public terminals of auxiliary contact 22) are switched to the side of diode 23.
As long as banked relay 2A (main contacts 20) disconnect, just no longer from AC power 3 to lighting load 4A supply alternating electromotive force and
Lighting load 4A extinguishes.In addition, when banked relay 2A auxiliary contact 22 (i.e. the public terminals of auxiliary contact 22) are switched
During to 23 side of diode, there is no reverse exciting current to flow, therefore photoelectricity three terminal bidirectional alternating-current switch coupler 14A light
Electric three terminal bidirectional alternating-current switch 141 ends.So, photoelectricity three terminal bidirectional alternating-current switch coupler 14A photoelectricity three terminal bidirectional is handed over
Stream switch 141 and banked relay 2A auxiliary contact 22 interlock, as a result, connecting with banked relay 2A main contacts 20
It is dynamic.That is, control unit 10 applies the signal voltage (F of reference picture 5) (t=t6 ') of pulse type to banked relay 2A.Cause
And control unit 10 control power supply 12 so that power supply 12 only be not shorter than banked relay 2A from closure state switch to beat
Supply electric power in the short time of the time of open state.
