1. A multi-speed multi-direction analog pointing device comprising:

  • a plus shaped upper contact having a central axis and having a number of ribs which radiate out from said central axis, and further wherein said upper contact has a bottom surface, and further wherein said bottom surface is electrically conductive;

    a substrate having an upper surface arranged below said upper contact and having a plurality of electrical contact points on said upper surface situated below said bottom surface of said plus shaped upper contact and aligned with said ribs; and

    displacement means for tilting and downwardly moving said plus shaped upper contact wherein said displacement means has an undeflected position and may be variably deflected when an external force is applied whereby electrical contact is made between said bottom surface of said plus shaped upper contact and at least one of said electrical contact points at a position corresponding to the direction and intensity of said external force.
