  • Electronic devices with improved switch assembly constructions
    Patent number: 8989824
    Abstract: Electronic devices are provided with housings that can have smoother profiles and with switch assembly input components with knobs that can move along tracks in directions at least partially offset from the directions of anticipated resistive forces. The housings can include switch assembly input components with knobs that may move along linear tracks and switch assembly input components with knobs that may move along curved tracks.

  • Phase flux barriers for transfer switch
    Patent number: 6919518
    Abstract: A transfer switch that includes output contacts, primary input contacts, secondary input contacts and a switch stack. The switch stack alternately connects the output contacts to the primary input contacts and the secondary input contacts via at least one conductive path. The transfer switch further includes at least one flux barrier that is at least partially positioned near the conductive path to minimize magnetic interaction with the conductive path as current travels through the switch stack.
