Abstract: An exemplary mechanically operated switching device includes at least one movable contact and an operating mechanism for coupling/separating the movable contact to/from a corresponding fixed contact. The operating mechanism includes first elastic mechanism for, upon release, providing the energy to separate the movable and fixed contacts. At least one shunt release having: a member movable between first and second stable positions, wherein movement from the first stable position to the second stable position releases the first elastic mechanism; at least a permanent magnet generating a force for holding the movable member in the first stable position, wherein the movable member held in the first stable position compresses a second elastic mechanism; and at least one electrical winding associated with the movable member and the electronic mechanism, which is configured to electrically drive the winding to generate a magnetic force that releases of the compressed second elastic mechanism.
