Abstract

A device for adjusting rotation angles, e.g. an electrical rotary switch (1), has a stator (2) and a rotator (3) mounted on the stator (2). The rotator (3) rotates between at least two rotational angle positions. The device has a magnet (4), e.g. a permanent magnet, which can be moved by the rotor (3), and a magnet field sensor (5), e.g. a Hall sensor, which together with the magnet (4) produces a signal which corresponds to the rotational angle position. The stator (2) has a receptacle (8) open on one side and shaped like a pot, with the receptacle (8) forming a rotating bearing for the rotator (3). The magnetic field sensor (5) is arranged in the receptacle (8) on the stator (2) and/or on a part which is mounted on the stator (2), such that the stator is a mount for the magnet field sensor (5).
