FIELD: construction.SUBSTANCE: locks do not have a conventional drive with the help of a mechanical key via a keyhole, and a place of lock installation is not visible from the side of the door, the keyhole itself is not available either. The key used is represented by electronic keys, such as contact ones, like magnetic cards and keyrings, and non-contact ones (radio-frequency, ultrasound, etc.) with different types of electronic codes. This provides for high protection against unauthorised break-in. The invention may also be used in the form of various actuating electromechanical mechanisms; manipulators, two-way relays, magnetic starters, traction mechanisms, an electromechanical trigger, hidden blockers of doors and anti-theft units of transport and other facilities.EFFECT: reliability improvement.21 dwg, 2 cl |
