Disclosed herein are a correction circuit for output duty of a Hall element, a Hall sensor, and a method of correcting the output duty of the Hall element. According to an exemplary embodiment of the present invention, the correction circuit includes an amplification and output unit for amplifying an output of the Hall element and outputting a sqaure wave signal; a duty detection unit for detecting a duty ratio of the sqaure wave signal output by the amplification and output unit; and a duty correction unit for applying a feedback correction signal to the amplification and output unit accoring to the detected duty ratio.

A contactless switching device has a permanent magnet which is rotatably mounted so that it is movable relative to a magnetic field dependent resistance which is located between the return poles of a return yoke. The permanent magnet is rotatably mounted in the manner of a rotatably mounted coil between the return poles of the return yoke and is magnetized in a diameter of the circle of rotation. Rotation of the permanent magnet varies the component of the magnetic field effective via the return poles between a maximum and substantially zero.

A system for controlling a magnetic switch in urinals includes a switch control unit and a control signal receiving unit connected to the switch control unit via a magnetic field. The switch control unit is configured to generate and eliminate the magnetic field based on a received pulse signal. The control signal receiving unit outputs an on signal in response to sensing the generation of the magnetic field and outputs an off signal in response to sensing the elimination of the magnetic field.
