Abstract

See full text

A miniature multiturn electrical capacitor is provided that includes low cost, high precision, die cast components and a unique spring biasing means to ensure electrical contact and torque between the rotor and the housing of the capacitor to enhance capacitor performance. The spring biasing means comprises a circular spring which resists compression in the radial direction and engages the inside surface of the flexible tubular rotor to bias the rotor against the internally threaded housing. The torque thus created promotes precise rotor positioning within and electrical contact with the housing.
