PROBLEM TO BE SOLVED: To provide a system for properly unlocking a door irrespective of electric control in an electric lock constituted so as to lock the door by electric conduction to an electromagnet.SOLUTION: An electric lock system A1 comprises: a door frame 6; a door 7 which performs opening/closing movement with respect to the door frame 6; an electromagnet 1 provided on the door frame 6; an attracted body 2 which faces the electromagnet 1 in the door 7 in closing of the door 7 and is attracted to the electromagnet 1 by electromagnetic attraction force in electric conduction of the electromagnet 1. The electric lock system A1 further comprises: a switch 4 which is provided in the middle of wiring 3 to the electromagnet 1 and can select a connection state or a cut-off state of the wiring 3 by mechanical external force; a switch changeover device 5 which is provided on the door 7 and performs locking/unlocking operations; and a movable part which is provided on the door 7, moves forward and backward with respect to the switch 4 so as to select the connection state of the wiring 3 in the switch 4 in the locking operation and select the cut-off state of the wiring 3 in the switch 4 in the unlocking operation in the switch changeover device 5. |
