A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count. As a result, the total number of magnets required in the system can be reduced, and the probability of failing to reset the Wiegand wire can be lowered.

An operation input device includes a resistance element to generate a capacitance between an operating medium and the resistance element in response to an approach of the operating medium to the resistance element, and a power source to supply electric charge to one end and the other end of the resistance element.
