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.

A process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board with the sliding rheostat slides along between two bonding pads, includes the following steps: outer layer etching; resin plugging: a. plugging the resinous ink into the pre-plugging position; b: baking, baking on the baking plate of the oven after the plugging is finished: board polishing: using a ceramic brush to process the plugged board, then using a non-woven fabric blush to polish the surface that is polished by ceramic brush. The present invention provides a process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board. The resin plugging method is used to plug the gap between the conductors of the sliding rheostat, so as to prevent the sliding rheostat from being unable to slide due to the altitude difference between conductors of the high-frequency signal board.
