Switching device including magnetic microswitches organized in a matrix

An electrical switching device, comprising:

• a plurality of magnetic microswitches organized in a matrix on a substrate, each magnetic microswitch including a mobile element driven between two positions and mounted onto one surface of the substrate, the electrical switch device including a network of crossed conducting lines, the magnetic microswitches being positioned near to intersections formed by the conducting lines, wherein
• the mobile element is configured to be held in a stable manner in each of its two positions under the sole effect of a permanent magnetic field generated for all the microswitches, the mobile element of each microswitch is formed of a ferromagnetic membrane that has two torsion arms anchored onto the substrate and the two torsion arms are completely enclosed within the perimeter of the mobile element, an interior end of a first torsion arm of the two torsion arms connects to a first anchoring pad located at an interior portion of the membrane, an interior end of a second torsion arm of the two torsion arms connects to a second anchoring pad located at an interior portion of the membrane, and exterior ends of the first and second torsion arms connect to exterior portions of the membrane, and
• the passage of an electrical control current, in a given direction, through two conducting lines, commands the change in position of the mobile element of the magnetic microswitch situated at the intersection of the two conducting lines.
