The device has a control element (9) i.e. rotary knob, movable with respect to a carrier (7) i.e. conductor plate. Permanent magnets (12, 15) are made of rare earth material and are carried along a movement path by the control element during a control movement of the control element. Counter elements (4) are respectively provided with ferromagnetic properties. The counter elements are arranged at a small distance to the magnets at the carrier and parallel to the movement path of the magnets. An alternately larger and smaller force acts on the magnets along the movement path of the magnets.
