Patent ID: 7893800

Claim:
A vehicle switch to be used in a vehicle, comprising: an external packaging; an operating unit accommodated in the external packaging so as to be movable linearly; a spring provided to urge the operating unit in a direction away from an inner bottom of the external packaging; a magnet mounted to the operating unit; a magnetic detector fixed with a distance from the magnet; a control circuit coupled to the magnetic detector; and a switching device to be electrically opened and closed by the control circuit, wherein the magnet and the magnetic detector are placed such that the magnetic detector senses a range of values of magnetic flux density from the magnet depending on an upper limit position and a lower limit position of the operating unit, and the control circuit electrically closes the switching device when the sensed value of the magnetic flux density is greater than or equal to a predetermined magnetic flux density value and electrically opens the switching device when the sensed value of the magnetic flux density is less than the predetermined magnetic flux density value.
