Abstract
A handle assembly for a joystick controller includes a tiltably mounted, elongated, hollow, tubular shaft having an elongated rod extending coaxially therethrough. A helical compression spring is seated in a recess at one end of the shaft and coaxially encircles the rod for engagement with an enlarged-diameter button thereon, resiliently to urge the rod to a normal rest position projecting a predetermined distance from the adjacent end of the shaft. Several different-shaped handle members are interchangeably mounted on the shaft, each handle member having a cylindrical bore therethrough for receiving the shaft and frictionally engageable with a knurled portion on the outer surface of the shaft. The bore has a reduced diameter portion at one end thereof to limit the depth of insertion of the shaft.
