Patent ID: 7999644

Claim:
A switch comprising: a switch body; and an operating member which is separated from the switch body, wherein the operating member is arranged and incorporated with a plurality of magnets, the plurality of the magnets being arranged to be different polarities between neighboring of the magnets, to have a magnetic pole of one side to be positioned on the side opposed to the switch body at a position where the switch body and the operation member are approached, and to have an opposite magnetic pole to be positioned on the opposite side of the side opposed to the switch body at the position where the switch body and the operation member are approached; and the switch body is arranged and incorporated with not less than three magnetic sensors in response to the polarities and the position of the magnets and the number of the magnetic sensors are more than the number of the magnets, and wherein each of the magnetic sensors give a detection output when the magnets are approached and placed in a detection region, at least one of the magnets is detected by more than one of the magnetic sensors in the detection region, and a switch output is generated on the basis of the detection outputs of all the magnetic sensors.
