Patent ID: 7852071

Claim:
A control element for a motor vehicle, comprising: at least one pivoted control knob; an extension formed on the control knob, the extension having the shape of a hollow cylinder, and having an end face, the end face being substantially orthogonal to a rotary axis of the control knob; an electrical device configured to detect a rotary movement of the control knob, the electrical device working together with the extension of the control knob, the electrical device being formed of at least two oppositely polarized magnets connected torsion-proof to the end face of the extension and by at least two sensors held stationary in the control element and detecting the magnetic field lines of the magnets, the at least two magnets axially elongating the extension from the end face; a cylindrically shaped seat, the cylindrically shaped seat comprising an internal hollow cylinder shaped part, an outer hollow-cylinder shaped part and a base connecting the internal hollow-cylinder shaped part and the outer hollow cylinder shaped part, the extension being arranged between the outer hollow cylinder shaped part and the internal hollow cylinder shaped part, the control knob being axially offset of the cylindrically shaped seat; a rotary bearing arranged between the internal hollow-cylinder-shaped part and the extension; and a printed circuit board, the base of the cylindrical shaped seat being attached to the printed circuit board, the end face connected to the at least two magnets being closer to the printed circuit than any other part of the extension.
