Abstract
An electrical switching device that can be employed in a sliding button, a rotating button, in a position switch, or an impact sensor. This device includes: a permanent magnet creating a magnetic field and a microswitch controlled between at least two states, by being aligned along two different orientations of field lines of the magnetic field of the permanent magnet. The microswitch and the permanent magnet are fixed relative to one another and a movable ferromagnetic part is moved between two positions so as to act on the orientation of the field lines generated by the permanent magnet so as to impose on the microswitch one or other of its two states.
