wherein the first and second contact points are in electrical contact with one another when the sun visor foot is in a mounted state in the receiving housing; and

wherein the conductive track comprises a stamping embedded in the receiving housing.

2. The attachment device according to claim 1 , wherein the protrusion is adapted to be pressed against the conductive track in a direction essentially perpendicular to the conductive track in the mounted state.

3. The attachment device according to claim 1 , wherein the conductive track is embedded in the receiving housing by injection moulding.

4. The attachment device according to claim 1 , wherein the sun visor foot is substantially surrounded by the receiving housing.

5. The attachment device according to claim 1 , wherein the attachment mechanism comprises at least one screw connection between the receiving housing and the sun visor foot.

6. An attachment device for a sun visor of a motor vehicle, comprising:

a receiving housing mounted on the motor vehicle,
