Hall sensor arrangement is disclosed for detection of the change in the
position of two components which can move relative to one another into
two end positions, with a Hall sensor with at least one Hall measurement
field (H; H1, H2) and a field magnet. An actuator is provided for
transmitting to the Hall sensor the change in the position of the two
components which can move relative to one another. The Hall sensor and
the field magnet are combined into a preassembled structural unit. When
the position of the field magnet changes relative to the Hall sensor from
one end position into the other end position the polarity of the magnetic
field acting on the Hall measurement field (H; H1, H2) can change, e.g.,
the polarity becomes reversed.
