A drive device for a part of a vehicle that can be adjusted between terminal positions, in particular the roof panel of a vehicle roof, having an electric motor that is connected to a pinion via a first step-down gear. A switch device that controls the electric motor for stopping the electric motor in at least one predetermined position of the adjustable part, and a second step-down gear that moves a switch body. A magnetic-field-sensitive sensor, controllable by the switch body, for controlling the switch device. A conductor track board inside a housing and extending with an extension over the path of motion of the switch element. The magnetic-field-sensitive sensor is disposed at a radial distance from the circular path of motion of the switch body and bridges the distance between the magnetic-field-sensitive sensor and the path of motion of the switch body by means of magnetic flux guide bodies. The magnetic flux guide bodies can be produced inexpensively of soft magnetic wire so that the conductor track board can be made with straight boundary edges, oriented at right angles to one another, in order to avoid waste.
A drive device (2) for adjusting a part of a vehicle between two terminal positions, comprising an electric motor (3) that is in driving communication with an adjustable part, a control switch device (9) that controls the electric motor (3) for stopping the electric motor (3) in at least one predetermined position of the adjustable part, a power takeoff element (31) that is rotatable at least indirectly by the electric motor (3), a switch body (32) that is secured to the power takeoff element (31) and is movable by the power takeoff element (31) along a circular-arclike path, a magnetic-field-sensitive sensor (35), associated with the controlling switch device (9), for controlling the control switch device (9), in which the magnetic-field-sensitive sensor (35) is disposed on a conductor track board (20) along with components of the controlling switch device (9), the conductor track board (20) is disposed inside a housing (6;
