Abstract
A multi-axial position sensor assembly for a joystick in which sensor/magnet pairs are positioned orthogonally on concentric gimbal rings such that each sensor and corresponding magnet pivot in relation to each other as a result of joystick movement. The sensors produce a reference output voltage when the joystick is centered and the sensors are aligned with the magnets. As a magnet rotates in relation to a sensor, the sensor produces an output voltage which is proportional to the angle of rotation and which has a polarity dependent upon the direction of rotation relative to the centered position.
