FIELD: electrical engineering; automatic magnetic-control switching devices. SUBSTANCE: sensor has case 1 with central bore accommodating magnetic control body 2, yokes 3, and armatures with magnets 6 uniformly arranged in case around central bore, as well as contact system. Each armature has rod 5 entering with clearance fit hole of respective yoke 3 fixed within case 1, and cam 7 with special slot 20. Sensor is provided with ring 14 placed in case 1 coaxially to central bore and carrying fixed pins 18 arranged in parallel with axis of ring 14. They carry shells 19 mounted for rotation. Pins 18 with shells 19 are installed for displacement along slot 20 of cam 7; slot 20 of cam 7 is made so that its plane of symmetry is parallel to axis of central bore of case 1 and spaced at angle from axis of rod 5. EFFECT: improved design. 6 dwg
