ABSTRACT:
A control device for a movable part, especially a sliding/tilting roof of a vehicle, comprises a motor for driving the movable part, wherein the terminals of the motor can be selectively connected to different poles of a power source by means of make-and-break contacts of corresponding relays, which make-and-break contacts each connect the corresponding terminal of the motor with the negative pole of the power source when the corresponding relay is not excited, and with the positive pole of the power source when the corresponding relay is excited. A first switch is provided, which is actuated through a control member driven by the motor and which interrupts the connection of the motor with the poles of the power source when the movable part reaches its closed position. A second manually operable switch with non-connected rest position is provided for alternately connecting one side of the excitation windings of both relays with the positive pole of the power source, whereas the other side of the excitation windings are directly connected with the negative pole of the power source. A switching circuit is provided, in which the first switch is connected and which, when the movable part reaches the closed position, excites the relay, which is not excited for operating the movable part.
