摘要： A potentiometer is provided having a cylindrical housing with an internal helical resistor groove having a helical resistance element disposed in the forward portion thereof. A rotor member having a resistance wiper element is disposed within the housing for contact with resistance element. A cylindrical end closure member having a raised external helical ridge thereon is threaded into the end portion of the helical resistor groove in the housing member. A rotor terminal pin is threaded radially into the housing member and through a radial aperture in the closure member to secure the closure member in a predetermined rotational relationship with the housing member and to align a stop shoulder on the closure with the housing member. A plurality of radially extending compression pads are formed on a forwardly facing shoulder of the closure member and engage a rearwardly facing shoulder on the housing member to enable the closure member to be rotated to a precise predetermined relationship with the housing while compensating for manufacturing tolerances in the fabrication of the housing and closure members.
