  • Patent number: 8466772
    Abstract: On the track of a potentiometer a resistive path of thin film is deposited or a foil is bonded to a matched substrate and a parallel path is formed of discrete contact straps extending from the resistive path. The resistive path has a protecting coating and the wiper is moving on abrasion resistant contact straps. This design enables application of high precision and stability resistor technologies in the production of variable resistors destined for long service life. It enables also, in high precision applications, by maintaining the linearity of the output versus input function, a two-wire connection to the variable resistor used as a position sensor.

  • Patent number: 6469613
    Abstract: A resistive element includes a resistive film disposed on an insulating film, a current collector disposed apart from the resistive film at a given space, and an electrode conductive to the resistive film and the collector respectively. The insulating board is punched to form slits which split the electrode. The slits allow the resistive element to maintain creepage distances between the electrode. The resistive element accommodates downsizing requirement while restraining silver migration for eliminating shorts between the electrodes. As a result, a highly reliable resistive element is obtainable.

  • Patent number: 5345215
    Abstract: A variable resistor device including a casing and a shaft slidably connected to the casing along its axis. The casing houses a resistive substrate and a slider which is movable along a surface of the resistive substrate. The casing also defines a pair of guide grooves for receiving protrusions extending from the slider, thereby restraining the slider to slide along a path defined by the guide grooves. One side of the slider contacts an end of the shaft, and an opposite side of the slider is pressed by a spring. The spring force is parallel to but spaced away from the axis of the shaft; therefore, the forces acting on the slider create a torque. Because the slider is not connected to the shaft, the slider pivots within a small clearance provided by the guide groove in response to the torque, thereby causing the projections of the slider to press against the walls of the guide groove and thereby preventing vibration of the slider relative to the casing.

  • Patent number: 4880950
    Abstract: A control switch having an air gap safety lever, a novel slide arrangement, and an illuminated on-off control switch. The air gap safety lever is mounted on the control switch in such a manner that no power may flow through the circuits until the unit has been installed and the front cover plate mounted. The slide arrangement employs a thin clip which provides an aesthetically appealing slide control, the clip having special dimples which allow nearly frictionless movement. The illuminated on-off control switch utilizes a light piping which conveys light from an LED to the on-off button, the light piping doubling as a mechanical link between the on-off button and a momentary contact switch mounted inside the control switch. Also, a novel frame is disclosed which secures all mechanical and electrical components of the switch together without the necessity of attaching the back box, which simplifies test and repair before shipment of the unit from the factory.

  • Patent number: 4132972
    Abstract: A miniature or subminiature, rectangular potentiometer which automatically disengages and engages at the extreme end settings may be fabricated by using a worm screw which engages and disengages a sector gear. The sector gear is arranged and configured to selectively engage a spring at the extremes of travel of the sector gear. When the worm screw drives the sector gear to the limit of its travel, the spring is compressed against the gear thereby compressing the spring. The compression of the spring is sufficient to permit the gear teeth on the opposing end of the sector gear to advance and disengage from the worm screw. Rotation of the worm screw in the opposing direction automatically re-engages the sector gear by virture of the urging of the spring.
