An electric pulse-controlled unit for a window raiser designed especially for use on an automobile, including a motor to raise and lower the window, a power circuit to activate this motor, a motor control capable of being moved from a cutoff position into first and second active positions in which the motor is activated respectively to raise and lower the window, and a mechanical control switch enabling selection of one of the active positions in order to operate the motor in the desired direction. Between each active position of the mechanical control switch and the power circuit for controlling the motor for raising and lowering the window, there is provided two circuits in parallel, each having a control flip-flop with a respective reset input connected in parallel by means of an OR logic circuit to a set of circuits comprising in particular: a delay circuit, a double control detection circuit, and a voltage loading detection circuit.
