  • Fader wheel for lighting control console
    Patent number: 6270239
    Abstract: A fader wheel assembly for a lighting control console includes a fader wheel having a single hub mounted at an acute angle to the top wall of the console. The inclined orientation positions approximately half of smooth, rounded outer wall and rim surfaces above the console top wall in an arrangement that is comfortable for the user. A single bearing locates the wheel as well as a transducer that is supported essentially only by its attachment to the fader wheel. Resilient arms lightly hold the transducer in position.
