SWITCHING DEVICE Russian patent published in 2007 - IPC H01H3/42 

FIELD: electrical engineering.

SUBSTANCE: proposed switching device has cam and microswitch with operating mechanism and two levers, each lever being hinged on one end to microswitch case. First lever is provided with external roller engageable with cam; second lever is disposed between first lever and microswitch operating mechanism and is engageable with the latter. Attachment points of levers are disposed on opposite ends of microswitch case and loose end of first lever is free to actuate second lever. First lever may have L-shaped end. Second lever can be made in the form of flat spring to cushion impact onto microswitch operating mechanism.

EFFECT: enhanced operating reliability of microswitch due to reduced differential travel of switching device.
