Abstract
An actuator comprises a permanent magnet body (1) and coil means for cooperation with the magnet body. The magnet body is rotatable about an axis of rotation (7) between, for example two, stop positions. The coil means exclusively comprise at least one active coil section (9a, 11a) of an electrical coil, which coil section extends parallel to the axis of rotation of the magnet body and substantially faces a magnet pole in a stop position of the magnet body.
