Abstract
A joy stick assembly is characterized by a joy stick resiliently mounted in an aperture through a hand holdable housing and normally biased to a neutral position. The joy stick is manually pivotable at one of its ends in any one of a plurality of directions through a 360.degree. arc, and has a conductive sphere at its opposite end. Four contacts are positioned at 90.degree. increments around the sphere and out of contact therewith when the sphere is in its neutral position, and the joy stick is manipulatable to establish electrical connections between the sphere and individual ones or adjacent pairs of the contacts to provide a signal from the sphere to the contact or contacts. With separate electrical connections established between the sphere and the four contacts and a tv video game, the joy stick is manipulatable to apply nine discrete signals to the game, four upon electrical connections between the sphere and individual ones of the contacts, another four upon electrical connections between the sphere and adjacent pairs of contacts and a further one when the sphere is in its neutral position.
