A bistable electromagnetic actuator comprising a magnetic circuit comprising a magnetic yoke in which a shunt extends perpendicularly to a longitudinal axis of said yoke and comprising a permanent magnet positioned between a first surface of the yoke and the shunt. A plunger core is fitted with axial sliding between a latched position and an unlatched position. A coil extending between the shunt and a second surface of the yoke is designed to generate a first magnetic control flux to move the plunger core from an unlatched position to a latched position. A second magnetic control flux enables the plunger core to move from the latched position to the unlatched position by the action of a return spring.

Bistable electromagnetic actuator, control circuit of an electromagnetic actuator with double coil and electromagnetic actuator with double coil comprising one such control circuit

The present invention relates to a stand-alone device for generating electrical energy comprising:&#x2014;an excitation coil () furnished with a central opening, &#x2014;a magnetic circuit passing through the central opening of the coil and formed of a fixed part () and a movable part () that can move with respect to the fixed part () so as to vary the magnetic flux through the excitation coil (), characterized in that, &#x2014;the magnetic circuit passes through the central opening of the excitation coil () several times, forming at least one loop. The invention also relates to a remote control device comprising a transmitter coupled to a remote receiver and a stand-alone device () for generating electrical energy so as to generate an electric current intended to power its transmitter.
