Abstract: The invention relates to a device for switching on and off an electric circuit comprising: a charge (5) which can be ignited, the combustion of which brings about the switching on or off of the electric circuit, ignition means for the pyrotechnic charge (5), characterized in that: the ignition means are connected to the electric circuit and the ignition means comprise a microswitch (M, M?) with magnetic action for controlling the ignition of the pyrotechnic charge (5).

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.

Abstract: A device for monitoring a position of a movable portion mounted on a casing of a switching electrical apparatus, the movable portion configured to adopt at least two determined positions. The device includes a permanent magnet and a reader including an antenna to interchange data without contact by electromagnetic coupling with a receiver element associated with the switching electrical apparatus. The receiver element includes an antenna controlled by a microswitch switched between two states depending on the position of the movable portion to establish or interrupt the electromagnetic coupling between the reader and the receiver element.
