Abstract: There is provided a single lever joystick having movement in X and Y directions and rotation about a further axis Z wherein axes X, Y and Z are substantially perpendicular. The joystick can be moved in all three senses at the same time. Movement of the joystick is resiliently restrained to a selected neutral position. Resiliency is obtained from substantially plate-like springy members to which are attached strain gauges. Each of the strain gauges is capable of producing a continuously variable electrical resistance output which is a function of the displacement of the joystick from its neutral position.
