ENERGY STORAGE FOR STEP-BY-STEM SWITCHING Russian patent published in 2006 - IPC H01H3/30 H01F29/04 

FIELD: electrical engineering.

SUBSTANCE: proposed energy storage for step-by-step switch has winding slide 8 actuated by drive shaft and driven part 9 actuating, in its turn, driven shaft running to load switch; winding springs 10 are adequately disposed between both parts. These both parts are installed for longitudinal displacement over guide rods 6, 7 disposed on one side one under other. Driven part 9 has toothed profile; its longitudinal movement upon releasing is converted by this toothed profile and engaged gear wheel 27 into rotary motion of driven shaft 28.

EFFECT: simplified design, reduced size, enhanced switch-over time of proposed energy storage contacts.
