The invention relates to a switch, in particular a vehicle switch, comprising a switching part which can be coupled to an actuation element, is rotationally mounted about a rotational axis and can adopt defined switch positions. The switching part comprises at least one permanent magnet comprising several south pole and/or north pole sections, and at least two magnetic field sensors which are arranged in a fixed manner in relation to the switching part. The output signals of said sensors, according to the switch position of the contact piece, is dependent upon whether a south or north pole section of the at least one permanent magnet is in the detection range of the respective magnetic field sensor and said output signals form an easy to determine binary switch code in the respective switch position. The invention also relates to an evaluation device for said type of switch, a switch unit comprising said type of switch and an evaluation unit.
