<p>A device for the remote controlled locking of doors has a motor 6, a switch 5 located in the energizing circuit of the motor 6 and a lock actuable by a key to control said switch 5. Actuation of the lock causes corresponding movement in a first mechanical element 2 which operates the switch 5 to start the motor 6. This moves a second mechanical element 9 having a collar 12 which abuts on an element 14 to move the first mechanical element 2 to complete the action of the lock. The collar 12 then passes past the abutment element 14. The device is built in one structural unit in a housing 1 for ease of installation. The switch 5 may be connected to similar devices in other doors to lock or unlock them simultaneously with the first door. <IMAGE></p> |
