ACTUATING SWITCHING DEVICE Russian patent published in 2011 - IPC H01H35/14 

FIELD: physics.

SUBSTANCE: actuating switching device has a housing, main and additional contact systems, a strap for the main contact system, an electromagnetic drive in form of a polar relay with reciprocal-rotary motion of the armature and a ratchet mechanism which is kinematically linked to said relay with possibility of stepwise rotation of the shaft. On one face of the strap there is a cam profile, having areas with constant and smoothly rising axial dimensions, which interacts from a force at the other end of the spring with radial projections, attached to the rotary shaft with possibility of axial back-and-forth movement of the strap when the shaft rotates, with successive interaction of attached current-conducting straps with contacts of the main contact system lying on two levels for extreme positions of the strap.

EFFECT: wider range of use by ensuring switching of a large number of electric circuits while preserving the size and weight characteristics and safety during emergency situations.
