  • Patent number: 5264821
    Abstract: A rotary, push-pull switch (20) for use in an automobile has a rotating ceramic coated metal substrate rheostat (48) and a supplemental switch (52) which opens and closes a dome light bypass circuit. The supplemental switch (52) is mounted internally to the rotary, push-pull switch (20) adjacent to the rotating rheostat (48) disposed on a shaft (36). A projection (88), which is radially disposed on the shaft (36), is used to actuate the supplemental switch (52) by engaging a resilient contact leaf (60) when the shaft (36) is rotated sufficiently. The engagement of the projection (88) and contact arm (60) causes the separation of a contact (62) and terminal (64), opens the dome light bypass circuit, and precludes energizing the dome light.

  • Patent number: 5237304
    Abstract: A magnetically sensitive switch is provided with an electromagnetic interference shield molded within the housing of the switch. In one embodiment, the magnetically sensitive switch is a vane switch for use in an automobile ignition system. The electromagnetic interference shield is formed by appropriately bending a flat sheet at a plurality of bend lines to form a box-like structure. The box like structure has five surfaces and one or more connection legs extending from one of the surfaces. One surface of the box-like structure also serves as a potting dam when a potting material is deposited into the cavity formed by the five surfaces during the process by which internal components are potted within the cavity of the EMI shield. The vane switch also includes a magnet encapsulated within its housing structure and spaced apart from the magnetically sensitive device within the EMI shield by a predetermined gap.

  • Patent number: 5144278
    Abstract: A circuit and apparatus for sensing the adjustment of a variable impedance device includes an elongated switching element having an alternating series of conductive and non-conductive areas. The conductive areas are electrically connected. As the device is adjusted, a wiper alternately operates the switch between open and closed states. A circuit detects the switch-state change and provides a signal which indicates that the device is being adjusted. The signal can, in turn, determine the output of a dimming circuit, a wireless transmitter, etc., or can determine whether power is provided to a microprocessor or the like. In another embodiment of the invention, a variable impedance device includes an end-of-travel return mechanism.

  • Patent number: 5075604
    Abstract: A variable resistance switch includes first and second flexible contact arms engageable by a pair of cam followers operable sequentially by an actuator movable in a first and an opposite direction. The actuator also carries a wiper movable therewith over a variable resistance coupled to a terminal. The first contact arm is operable upon initial movement of the actuator in a first direction to complete a first circuit through the switch, and the second switch arm is operable upon further movement of the actuator in the first direction to complete a second circuit through the switch and to place the variable resistance in circuit between one of the switch arms and the terminal. Further movement of the actuator in the first direction is operable to move a wiper over the resistance to vary the resistance in circuit with the terminal. A pivotal trigger is coupled to the actuator for moving the same in the first direction, and a spring biases the cam in the opposite direction.

  • Patent number: 4947054
    Abstract: A system for controlling power to an electrical load includes a linear slide dimmer and a switch, whose pushbutton actuator moves up and down with the dimmer slider. When the pushbutton is depressed, to actuate the switch, it rides in and out in the slider. The slider only moves up and down. In one embodiment, a light is visible through the pushbutton in a darkened environment. In another embodiment, a wallbox-mountable switch assembly includes a pushbutton-actuated, alternate-action mechanical power switch whose pushbutton, when depressed, moves within a bezel that is attached to the switch support.

  • Patent number: 4903003
    Abstract: A variable resistor with a switch which minimizes appearances of an arc and prevents incomplete contact between contacts of the switch originating from such an arc. The variable resistor with a switch includes a torsion coil spring having one end connected to a movable contact element supported for pivotal motion around a support shaft and the other end connected to a cam member also supported for pivotal motion around the support shaft. When the cam member is pivoted by movement of a slider receiver, a connecting point between the torsion coil spring and the cam member moves across a straight line interconnecting the support shaft and another connecting point between the torsion coil spring and the movable contact element so that a movable contact on the movable contact element is instantaneously brought into or out of contact with a fixed contact to turn the switch on or off irrespective of the speed of movement of the slider receiver.
