Abstract
A contact switch for a kinetic activity amusement game has a base, a universal joint connected to the base and a contact bumper connected to a ball of the universal joint. A electrically conductive coil spring has one end connected to the ball of the universal joint and a second end retained by the base. An electrode has contact portions disposed radially around the coil spring. A power source is connected between the coil spring and the electrode forming a potential electrical circuit. Displacement of the contact bumper by kinetic energy of a game ball causes displacement of the coil spring and contact of the coil spring with the contact surfaces of the electrode closing the circuit.
