Abstract
A novel joy stick in which arcuate shaped resistors are biased against conductive coil carried by a ball. The arcuate shaped resistors have electrical contacts that extend from them. Tactile feel is obtained by providing detent means that give the ball a suitable feel as it is moved.
Claims6
A joy stick comprising, lower and upper ball receiving members, a ball mounted between said lower and upper ball receiving members, a conductive path attached about the periphery of the ball, a slot formed in said lower and upper ball receiving members, and a contact member receivable in said slot, said contact member formed with an arcuate resistor which is engageable with said conductive path attached to said ball, including spring biasing means connected to said lower and upper ball receiving members and to said contact member to bias it toward said conductive path, including a plurality of slots in said lower and upper members, a plurality of contact members receivable in said plurality of slots and each formed with arcuate resistors engageable with said conductive path on said ball, and said spring biasing means biasing said plurality of contact members toward said conductive path, and wherein said ball is formed with an annular groove, and said conductive path comprises a coil of electrical conductive material mounted in said groove.
