Abstract
A joystick includes a shaft having a handle at one end and an actuator at the other end and pivotally mounted on a base for universal pivotal movement to actuate a plurality of switches. A bearing sleeve having a very low coefficient of friction is telescopically disposed between the shaft and the actuator coaxial with each and freely rotatable relative to each so that the actuator is substantially unresponsive to rotational movements of the shaft about its axis. The actuator is trapped between a flange on the bearing sleeve and an E-clip on the end of the shaft, the clip also retaining the bearing sleeve on the shaft.
