IMMEDIATE ACTION SWITCH Russian patent published in 2012 - IPC H01H36/00 

FIELD: electricity.

SUBSTANCE: in a switch of immediate action comprising a body, at least one contact unit driven by a magnet unit, capable of displacement in a body, and a driving element with a source of control magnetomotive force, differing by the fact that it is equipped with two magnetic conductors fixed in the body and spaced in direction of driving element displacement, and the magnetic unit is also arranged as a source of control magnetomotive force, in the form of two permanent magnets, installed with identical poles onto a common pole tip, and additional pole tips adjacent to other poles of the specified magnets, besides, common pole tips of each magnet unit and source of the control magnetomotive force are placed between specified magnetic conductors as capable of displacement between them, besides, the magnetic unit and the source of control magnetomotive force are covered with shells, one of which movably interacts with a spring-loaded driving element, at the same time the contact unit interacts with the magnetic unit via a plate of electric insulation material.

EFFECT: higher accuracy of a switching diagram and device reliability.
