ABSTRACT:
A curved disc joystick or pad with improved performance, reliability and durability can be used as a cursor pointing device for computers, remote controls, video games, consumer electronics, industrial controllers, automotive and other applications. A conductive spring or sheath connects to a conductive curved rubber transducer which can be deflected to make contact with conductors on a printed circuit board, providing electrical outputs to a microprocessor or other device. A ribbed locking extension may be added to automate the assembly process. In addition, a collar may be provided to produce a controllable product, both in terms of manufacturing and performance.
