Abstract: A microsystem, including a magnetic microactuator, with a mobile element supported by a substrate and controlled by magnetic effect between a first position and a second position for switching at least one electric circuit. A permanent magnet or a solenoid subjects the mobile element to a first uniform magnetic field to hold the mobile element in the first position. An energizing coil external to the substrate, on energizing, subjects the mobile element to a second magnetic field to move the mobile element from the first position to the second position, the energizing coil being of solenoid type and surrounding the substrate supporting the mobile element.

Abstract: The invention relates to a microsystem, comprising a magnetic microactuator (2, 2?), with a mobile element supported by a substrate (3) and controlled by magnetic effect between a first position and a second position for switching at least one electric circuit, whereby a permanent magnet or a solenoid subjects the mobile element to a first uniform magnetic field (B0) to hold the same in the first position, an energising coil (4, 6), external to the substrate (3), said energising coil (4, 6), on energising the above, submits the mobile element to a second magnetic field (BSi) to move the mobile element from the first position to the second position, the energising coil being of the solenoid type and surrounding the substrate supporting the mobile element.
