SWITCHGEAR AND SWITCHGEAR ACTUATOR Russian patent published in 2015 - IPC H01H33/42 

FIELD: machine building.

SUBSTANCE: switchgear actuator actuates a mobile contact designed with a possibility of a reciprocative movement for switching of the switchgear between the states "on" and "off". Meanwhile the solenoid lever (36) is pushed and rotated by the electromagnetic solenoid plunger (38a) for cutting off (38), so that the solenoid lever (36) turns counter the direction of return spring (37) action of the solenoid lever. A starting roller pin (31a) and the solenoid lever (36) are disjoined with each other. An eccentric pin (32) and the starting levers (31) turn due to forced action from the latch forward end (34c) and are disjoined from each other, therefore the latch lever (12) turns by means of released energy of the cutting off spring.

EFFECT: decrease of period of time necessary for release of elastic breaking force, total period of time of contact breaking in the switchgear.
