Conventionally, this type of electric lock/unlock device has a built-in actuator (rotary solenoid, etc.) and
It has been proposed that a thumb turn 62 from which a lead wire 63 for power supply to the actuator is led out is attached to the lock housing 61 (Fig. 6). In such a device, the actuator is supplied with power from an external device such as an electric lock controller. By supplying voltage, the deadbolt 64 is moved out and out of the lock housing 61 to lock and unlock the lock.

When installing on doors with different hands, it was necessary to reverse the polarity of the 7-cut unit between right-hand and left-hand, and for this purpose a changeover switch was installed in the controller and the wiring was changed. .

[Problem to be solved by the invention]

However, with such conventional devices, there are problems in that the wiring of the changeover switch is troublesome, the deadbolt is likely to malfunction due to a mistake in reconnecting the wiring, and the lead wire is drawn out from the actuator. The appearance was spoiled due to the

The present invention can eliminate the work of changing the changeover switch and wiring, and furthermore, when using a mechanical lock as an electric lock, the electric thumb turn can be attached to the lock housing extremely easily. The purpose of the present invention is to provide an electric thumb turn, a lock housing, and an electric lock/unlock device.
