This invention discloses a type of noncontact linear potentiometer; the potentiometer comprises a slider, a rotating shaft, a guide rod, a tunneling magnetoresistive sensor, a permanent magnet, a printed circuit board, and two support structures. In this configuration the slider moves along the guide rod and the rotating shaft, causing the rotation of the rotating shaft; the permanent magnet is attached to an end of the rotating shaft, and it therefore rotates as the shaft rotates. A tunneling magnetoresistive sensor is located adjacent to the permanent magnet, soldered onto a printed circuit board, and it is used to measure the angle of rotation of the permanent magnet. The guide rod constrains the sliding direction of the slider, and the two support structures are located at the opposite ends of the guide rod and rotating shaft, and they are used to support the rotating shaft and guide rod. Located between the slider and rotating shaft is a ball bearing, a pin and a leaf spring assembly. This potentiometer has several advantages, including a compact structure, easy fabrication, long service life, in addition to providing smooth slider motion that provides a pleasing user experience.

A vehicle pedal with a contacting sensor that comprises a pedal arm coupled to and rotatable relative to a pedal housing. A rotor includes a first end coupled to the pedal arm and an opposed end with contactors abutting and adapted to slide against a resistive element in response to the rotation of the pedal arm. A head on the rotor includes means for preventing the over-deflection of the contactors. In one embodiment, the means for preventing the over-deflection of the contactors comprises an extension on the head of the rotor that defines a stop limiting the deflection of the contactors. In another embodiment, the means for preventing the over-deflection of the contactors comprises the combination of a tab on the head of the rotor and a wall in the interior of the pedal housing. The tab abuts against the wall and prevents the movement of the rotor in the direction of the resistive element.
