ROTARY MAGNET

A bistable rotary magnet is proposed, comprising a rotor, wherein the rotor comprises a permanent magnet having differently polarized magnetic poles opposed with respect to the axis of rotation, wherein the stator comprises two pole shoes extending along the axis of rotation, wherein the permanent magnet includes a first pole surface and a second pole surface at each magnetic pole and each of the two pole shoes includes a first pole surface and a second pole surface, wherein in the first end position the first pole surfaces of the permanent magnet are aligned in parallel to the adjacent first pole surfaces of the pole shoes and in the second end position the second pole surfaces of the permanent magnet are aligned in parallel to the adjacent second pole surfaces of the pole shoes.
