An electromagnetic actuator comprises a yoke, a core, at least two windings and switching means of the windings from a series position to a parallel position and vice-versa. It comprises control means comprising regulating means of the electric current flowing in the windings. The control means comprise inrush means controlling the voltage supplied to the windings during a closing operation, and controlling the switching means to place the windings in parallel mode. The control means also comprise holding means controlling the current supplied to the windings during a holding operation of the actuator in the closed position and controlling the switching means to place the windings in series mode.
