Abstract:
1. A bistable magnetic actuator, comprising: a first fixed magnetic structure including a first conductor coil surrounding a first open magnetic circuit having a first end and a second end; a second fixed magnetic structure including a second conductor coil surrounding a second open magnetic circuit having a first end and a second end, the first ends of the first and second magnetic circuits being arranged opposite one another; and a mobile magnetic part located near the first end of the first magnetic circuit and the first end of the second magnetic circuit, the mobile magnetic part being fixed to non-magnetic means allowing movement of mobile magnetic part in the direction of the first end of the first magnetic circuit or in the direction of the first end of the second magnetic circuit, and being capable of occupying a first or a second stable working position depending on whether the first or second conductor coil is excited; wherein for each magnetic circuit, the first end and the second end have faces positioned along planes perpendicular to one another, and the second ends of the first and second magnetic circuits have faces arranged along one same plane or which merge.
