  • Apparatus for assembling and holding a potentiometer assembly
    Patent number: 5079537
    Abstract: A support plate for mounting one or more potentiometers includes a receptor for receiving a potentiometer and alignment tabs for guiding the potentiometer into position and preventing it from rotating during mounting. The potentiometer may be secured to the alignment plate through the application of clamping force produced by torquing a lock nut on the threaded stem of the potentiometer. The alignment tabs prevent the potentiometer from rotating during the application of the clamping force so that the contacts of the potentiometer maintain a predetermined position.
