Abstract: A joystick mechanism for transducing vector motion of an end of a joystick into its X and Y components including: an X-potentiometer having a body and a shaft, a bracket for mounting the body of the X-potentiometer to a surface, a Y-potentiometer having a body and a shaft, a rod connecting the shaft of the X-potentiometer to the body of the Y-potentiometer so that the shafts of the X and Y-potentiometers lie at right angles to each other, and a joystick having one end attached to the shaft of the Y-potentiometer and which is oriented such that its effective axis lies at a right angle relative thereto.
