Abstract
A switching device includes: a housing; a moveable element, including a header and first and second magnets, slidable in the housing, the moveable element moveable between released and engaged positions; and a microcontroller and first and second magnetic sensing elements facing the first and second magnets. The first and second magnetic sensing elements detect respectively first and second magnetic fields generated respectively by the first and second magnets. A pole configuration of the first magnet is opposed to a pole configuration of the second magnet and the first magnetic field is reversed and equal in magnitude to the second magnetic field. The microcontroller is able to validate that first and second output signals produced by the first and second magnetic sensing elements, respectively, from the first and second magnetic fields are reliable for determining a position of the moveable element.
