Abstract

The actuator has an electromechanical transducer (3) formed by an electromagnetic induction coil with connection terminals (31, 32). The transducer generates a magnetic field having a main direction, in an influence zone, under the effect of an electric current circulating between the terminals. A mobile conductive bar (2) is electrically placed between the terminals and extends in the zone, transversal to the direction. The transducer has loops (3A, 3B) that are placed on the bar and exert a Laplace force, oriented towards a direction, on the bar, to move the bar away from studs (11, 12).
