Patent ID: 8193884

Claim:
An electrical switching device, comprising: a permanent magnet that creates a magnetic field; a microswitch including a moving element driven by a magnetic effect between at least two states by being aligned according to two different orientations of field lines of the magnetic field of the permanent magnet, wherein the microswitch and the permanent magnet are fixed relative to each other; a moving ferromagnetic part configured to move between two positions in a direction perpendicular to a direction of magnetization of the permanent magnet and displace a plane of symmetry of the field lines generated with respect to the moving element by the permanent magnet to impose on the moving element one or other of its two states, wherein a direction of displacement of the plane of the symmetry corresponds to the direction of movement of the ferromagnetic part, wherein in an initial position, the ferromagnetic part is maintained by a magnetic effect to be in physical contact against the permanent magnet and at least a portion of the ferromagnetic part is above and parallel to the permanent magnet.
