FIELD: ironmongery. SUBSTANCE: invention refers to locks having cylindrical coil, ferromagnetic bar core located inside coil and kinematically coupled to nonmagnetic working pin, element to fix core in its extreme positions corresponding to open or closed state of lock. Core comes in the form of permanent magnet and element to fix core has shape of magnetic core mounted for attraction and holding core in position corresponding open or closed state of lock. At least part of magnetic core is positioned with clearance relative to side surface of core to ensure their magnetic interaction. EFFECT: lock displays increased operational reliability. 3 cl, 3 dwg
