  • Publication number: 20030173199
    Abstract: An electric switch requiring mechanical movement for actuation is mounted to a surface mountable switch mounting plate by standoffs so as to position a switch actuation element in position for actuation by a planar switch cover plate adapted for sliding engagement, in parallel juxtaposition, with the switch mounting plate. The switch cover plate is adapted for engagement with the electric switch for actuation thereof by sliding engagement.
    Type: Application

  • Patent number: 6534734
    Abstract: An electric switch requiring mechanical movement for actuation is mounted to a surface mountable switch mounting plate by standoffs so as to position a toggle bat in position for actuation by a planar switch cover plate adapted for sliding engagement, in parallel juxtaposition, with the switch mounting plate. The switch cover plate is adapted for engagement with the electric switch for actuation thereof by sliding engagement.

  • Patent number: 6459250
    Abstract: A circuit board provides a first elevation adapted for printing and bonding of conductor and resistor traces and monolithic ceramic capacitors, and provides through holes adapted for locating conductors. A second elevation is adapted for location and containment of a semiconductor quadrac. A third elevation is adapted for location and containment of a circuit board which is selectively adjustable through an R-C network coupled between the semiconductor quadrac and an input power source. An electric phase control uses mechanical movement for actuation. Provision is provided for mounting the phase control mechanism and the circuit so as to be manually accessed. A planar switch cover plate is adapted for sliding engagement, in parallel juxtaposition, with the mounting devices, the switch cover plate further adapted for engagement with the phase control mechanism for actuation through sliding engagement.

  • Patent number: 5731663
    Abstract: A variable power lamp control adapter is provided having a novel, different, and a lower cost construction method than that used in prior art lamp control devices. The circuit construction is achieved by utilization of the Surface Mount Technology disciplines of Polymer Thick Film and Chip on Board technologies. The adapter circuitry is constructed and held on a uniquely dissimilar type of substrate than that used in prior art, and assembled into housings that contain unique interengaging mating parts for a more rapid assembly process than the assembly processes used in prior art construction. In the present invention an overall improvement in the organization, arrangement of all componets, housings and assembly is achieved for a reliable power control operation.
