Embodiment Construction

[0034] The invention will be described with reference to Figures 1-7.

[0035] As described in the prior art above, the microsystem according to the invention uses magnetic microactuators 2, 2' to control the opening or closing of circuits.

[0036] Referring to Figures 2A and 2B, the microsystem comprises microactuators 2, 2' The substrate 3 is manufactured, for example, from a material such as glass, plastic or a good thermal conductor based on silicon or ceramics for applying electricity. The substrate 3 has a planar surface 30 on which the microactuators 2, 2' are fixed. As is known (see patent application US 2002 / 0140533), the substrate 3 carries, for example, at least two electrodes 31 , 32 for electrical connection to close an electric circuit ( FIGS. 2A and 2B ). To achieve this, the magnetic microactuator 2, 2' carries at least one movable contact 21, 21' capable of electrically connecting the two electrodes when the microactuator 2, 2' is activated 31, 32.

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.

Description

technical field [0001] The invention relates to a microsystem comprising at least one magnetic microactuator actuated by means of an external excitation coil. Such microsystems can be used as electrical interrupters, especially of the switch, contactor or relay type. Microsystems of this type are particularly suitable for production in MEMs technology. Background technique [0002] Document US 6 320 145 describes an electrostatic relay. The relay is operated by means of a magnetizable and monostable lever. Under the action of a magnetic field, the rod bends, tending to align in the direction of the magnetic field and close the electrical circuit. Since the rod is made of elastic material, the rod returns to its original position only mechanically when there is no magnetic field / rod interaction. The restoring force on the rod returning it to the original position is therefore of purely mechanical origin and is produced only by the nature of the material used to manufactur...
