FIELD: electrical engineering; control devices including those preventing movement of control device components with external drive.
SUBSTANCE: proposed device has case 1 with cover 7 accommodating control rod 16 installed in guides between cover 7 and case 1; ball 14 mounted in hole of case 1; and control drive. Novelty is that device is provided in addition with diaphragm 13 tightly sealed under ball 14 in case hole; retainer 10 fitted between diaphragm 13 and internal boss 8 on cover 7 coaxially with armature 17; E-shaped spring 15 secured on control rod 16 to press control rod to case 1 and ball 14, to diaphragm 13 and to rotary retainer 10. Control drive is made in the form of rotary electromagnet incorporating bistable polarized electromagnetic system; spring stops 20 are installed at ends of armature 17 with carriers 19 of control drive.
EFFECT: simplified design and enhanced reliability of device incorporating electromagnetic drive.
