ABSTRACT OF THE DISCLOSURE A positional transducer element and an orientation of two positional transducer elements within an X-Y position indicator for a display system. An X-Y position indicator which control the movement of a cursor over a display on a cathode ray tube. Signals are generated from the indicator indicating its position to cause the cursor to be displayed on the tube at a corresponding position. X and Y position wheels are mounted within the indicator at a predetermined relationship to each other and a contact surface for rotation according to the X and Y movements of the indicator. The X and Y wheels are respectively coupled to transducer elements which translate the rotation of the wheels into X and Y positional signals.
