A control element is provided for a motor vehicle, particularly a rotary actuator, having at least one pivoted control knob, an extension formed on the control knob, and an electrical device to detect the rotary movement of the control knob, whereby the electrical device works together with the extension of the control knob, and whereby the electrical device is formed of at feast two oppositely polarized magnets connected torsion-proof to the extension and by at least two sensors held stationary in the control element and detecting the magnetic field lines of the magnets.
