Abstract
In this control box, a first switching device (R-1) is actuated when the operator acts on a selector (1) whereby he can choose, on one hand, the direction of the driving of the motor (9) and, on the other hand, by means of a brief or prolonged action, the driving speed of this motor. If the action is prolonged, the switching device (R-1) is inhibited by a second switching device (R-2) controlled by a timing circuit (27) which was initiated at the start of the action. This second switching device then supplies power to the motor (9) through a series resistor (18) so long as the selector (1) is actuated. Application in an electric window raiser of an automobile vehicle.
