Actuator for controlling an element along at least two degrees of freedom

The drive (1) has a motor (3) for an actuating part (2) and a printed circuit board (10) with potentiometers (6) with resistance tracks and brushes. The board consists of a conductor plate (11) imbedded at least partially in plastic for electrical connection of the ends of the resistance tracks to contact points. The track sections between the ends are supported by the plastic. The brushes are held on carriers (15), e.g. toothed gears, friction pulleys, or cranks, and are in operational connection with a reduction gear (5) and/or the actuating part. The plate is angled so that the resistance tracks are located in different planes. Conductor plate with potentiometers and contact points form a modular unit.
