Abstract

A device for displacement of a movable part on motor vehicles such as sliding roofs, windows or the like including an electrical servomotor permanently mechanically coupled to the movable part and a supply circuit adapted to operate the electrical servomotor and to brake the electrical servomotor by short circuiting the electrical servomotor when the movable part reaches a desired position, where the supply circuit includes an isolating device for breaking the supply circuit to prevent short circuit braking of the electrical servomotor thereby allowing manual displacement of the movable part.
