Abstract
A joystick controller has a body 12 including an end wall 18 in which is secured a resilient arm 10. The resilient arm 10 has secured to its top a tube 90 and a handle 94. The tube 90 surrounds to arm and mounts an annular magnet 38 at the level of a pivot point 96 about which the arm 10 flexes. The outputs of Hall effect probes 26 are affected by the position of the magnet 38 to give an indication of the position of the arm 10. The angular position of a rotary handle 80 is sensed using a magnet 110 which is connected for movement with the handle 80 relative to further Hall effect probes 116 (FIG. 9).
