Abstract: A trimming potentiometer comprising a base with a flange extending perpendicular to it and a cover that encloses the flange and is sealed to the base. Supported on the flange is an assembly comprising a post, a non-conductive plate on which an arcuate resistive path is disposed, a contact plate with a contact finger that presses against the resistive element, and a gear journaled on the shaft and releasably coupled to the plate to move the finger along the arcuate resistive path. The shaft, the plate and finger, and the gear are joined together, and a spring is provided to force the plate into engagement with the gear. The cover has a lead screw mounted in it with a head available to the outside and the threaded portion in mesh with the gear. The axial direction of the screw may be either perpendicular to the base or parallel with it.
