Next, the operation of this electric lock device will be explained.

From the power supply E of the electric lock body, relay contact ry ₁ ,
Even if power is supplied to the secret switch section through ry ₂ and electric wires L ₁ and L ₂ , and the input voltage polarity to the secret switch section is reversed by switching the relay contacts ry ₁ and ry ₂ , the diode bridge DB Therefore, a power supply voltage of the same polarity is always applied to the logic processing section LP.

When the locking operation is performed, the logic processing section LP of the secret switch section is activated and the locking/unlocking signal contact _S1 is turned on, and the locking signal (positive voltage) is transmitted to the electric wire.
Locking/locking the processing part P of the electric lock body through L ₃
The unlocking signal is applied to the input terminal _P2 , and the processing section P performs the locking operation. Also, when an unlocking operation is performed, the logic processing section LP is activated and the locking/unlocking signal contact _S1 is turned off, and the unlocking signal (no voltage) is passed through the electric wire _L3 to the locking/unlocking signal of the processing section P. It is applied to the input terminal _P2 , and the processing section P performs the unlocking operation.

On the other hand, when the security set operation is performed, the logic processing unit LP is activated and the security set/reset signal contact is activated.
_S2 is turned on, a security set signal (positive voltage) is applied to the security set/reset signal input terminal _P3 of the processing section P, and the processing section P performs the security setting operation. When this security set operation is completed, a security set completion signal is output from the security set completion signal output terminal _P1 , turns on transistor TR, energizes relay RY, and switches relay contacts ry ₁ and ry ₂ from the NC side to the NO side. Switch to As a result, the polarity of the voltage applied to the terminals T ₁ ' and T ₂ ' of the secret switch section becomes the forward polarity with respect to the light emitting diode LED, indicating that the security setting has been completed.

Also, when the security reset operation is performed, the logic processing unit LP is activated and the security set/reset signal contact _S2 is turned off, and the security reset signal (non-voltage) is activated.
is applied to the security set/reset signal input terminal _P3 , and the processing section P performs the security reset operation. When this security reset operation is performed, the processing unit P stops outputting the security set completion signal and resets the transistor TR.
Turn off, stop excitation of relay RY, and switch relay contacts ry ₁ and ry ₂ to the NC side. As a result, the voltage polarity between the terminals T ₁ ′ and T ₂ ′ of the secret switch portion becomes opposite to that of the light emitting diode LED, and the light emitting diode LED is turned off.

As a result of this configuration, the two electric wires L ₁ and L ₂ for supplying power from the electric lock body to the secret switch are connected to the security set completion signal from the electric lock body to the secret switch. It can also be used for transmission, and by simply wiring the electric lock body and the secret switch with four electric wires _L1 to _L4 , one less than the conventional example, the secret switch can be connected from the electric lock body to the secret switch. It is possible to supply power to the electric lock and send a security set completion signal, and also send a lock/unlock signal and a security set signal from the secret switch to the electric lock body.
A reset signal can be sent. Therefore,
Wiring between the electric lock main body part and the secret switch part can be done with an easily available 4-core electric wire, making construction easier and reducing costs because the number of terminals is small. Furthermore, the probability of incorrect wiring is also reduced.
