SWITCHING DEVICE Russian patent published in 2014 - IPC H01H3/42 

FIELD: electricity.

SUBSTANCE: switching device comprises a cam, a microswitch with two driving elements and a lever, one end of which is hingedly fixed on the microswitch body, and the other one is equipped with a roller capable of interaction with the cam. The end of the lever comprises a cog that may interact with one driving element during lever rotation. In the central part of the lever there is a screw installed rigidly, arranged as capable of acting at the other driving element in process of lever rotation. As the cam acts at the roller, the lever presses first one driving element, which indicates the position, and then the second driving element, which sends a signal to disconnect the electric actuating mechanism.

EFFECT: expanded area of device usage due to provision of the possibility to indicate position of an electric actuating mechanism and subsequent supply of a signal for its disconnection.
