  • Patent number: 4951378
    Abstract: A process of automatic sequential production of potentiometers, and potentiometers obtained thereby. The potentiometers are generally low profile rotary-type potentiometers. The potentiometers are formed with a low profile cylindrical casing into which is inserted a laminate electrical resistance element of an incomplete annular shape, the ends of which remain connected to terminals. The casing engages a slider, which is in permanent mechanical and electrical contact with the resistance element and a collector terminal. The slider is assembled on a slider-holder rotatably attached through an aperture formed axially through the body and which is operable from the external surface of the casing. The process consists of automatically assembling the potentiometers in an in-line process. The metallic components are formed on a continuous metallic band by die-cutting the band to produce such components.

  • Patent number: 4736184
    Abstract: The direct connection potentiometer includes a block of electrically insulative material having two opposite faces and an edge about the perimeter of the faces. An electroresistive track is provided in an arc on the front face of the block, radially spaced from a ring-shaped conductive area provided on that face. Conductive strips extend from each end of the track, and from the ring-shaped conductive area to the perimeter of the front face, where each, spaced from the others, wraps around the edge of the block to its rear face. A rotatable cursor, i.e. a slide is mounted to the block centrally of the ring-shaped conductive area and connects the ring-shaped conductive area with a selected arcuately short portion of the electroresistive track.
