FIELD: electrical engineering, magnetically controlled switch gears for automatics. SUBSTANCE: break-off sensor includes case 1 with central hole where controlling magnetic body 2, casings 3 and armatures with magnets 6 are uniformly arranged and contact system. Each armature has rod % entering while fitted with clearance hole of proper casing 3 made fast to case 1 and cam 7 with special groove. Sensor is provided with ring 14 placed in case 1 uniaxially to central hole having pins rigidly attached to it and placed in parallel to ring axis. Inserts are mounted on them for rotation. Pins with inserts are positioned for movement along groove of cam 7. Groove of cam 7 of armature is so fabricated that its symmetry axis is parallel to axis of central hole of case 1 and is placed at angle α to axis of rod 5. EFFECT: enhanced stability to mechanical action. 1 dwg |
