A joystick controller has a body ( 10 ), an operating shaft ( 12 ) and a ball-and-socket joint ( 14 ) mounting the operating shaft for universal pivotal movement relative to the body ( 10 ) about a pivot center. First and second and third carrier members ( 16, 17, 19 ) are movable relative to the body ( 10 ) about respective first, second and third, mutually perpendicular axes which pass through the pivot center of the ball-and-socket joint ( 14 ), and carry respective magnets ( 24, 26, 29 ). Rotary movement of the operating shaft ( 12 ) about its longitudinal axis causes movement of the third carrier member ( 19 ) about the third axis. Hall-effect devices ( 52, 54, 56 ) are mounted on a common planar circuit board ( 48 ) at the base of the body ( 10 ) and producing respective output signals indicative of the positions of the magnets ( 24, 26, 29 ) carried on the first, second and third carrier members ( 16 ), respectively. |
