Abstract:
1. An apparatus for generating a data signal, the apparatus comprising: a housing; means for coupling a first controller to the housing so that the first controller may move from a home position to a plurality of positions radially extending from the home position comprising a dome plate coupled with the first controller, the plate including a plurality of cantilever arms that matingly engage an upper surface of the housing to create a bias when the first controller is coupled to the housing and a director plate coupled with the dome plate, the director plate including a post affixed to a cantilever arm that fits within an aperture formed in the dome plate when the dome plate and director plate are coupled together; means for guiding the first controller among the home position and the plurality of positions radially extending from the home position; and means for sensing a position of the first controller and generating the data signal in response to the first controller being moved from the home position to one of the plurality of positions.
