Cursor controller
A cursor controller used to control displacement direction and speed of a cursor by changing equivalent capacitance comprises a conductive layer, two electrode layers and a press body. The electrode layers are attached to each face of the conductive layer respectively, wherein a plurality of electrode lines is formed on each electrode layer; one end of each electrode line is coupled with a resistor, and a vector zone is formed on each electrode layer at a section without connected resistor to cross each other perpendicularly in different orientations. An insulation portion is printed on a peripheral area of the electrode lines and on the resistors. The conductive layer and the electrode layers are glued together to form a thin-film printed circuit board. When the press body is pressed against the electrode layer the conductive layer will contact the electrode layers to effect a matrix output signal.
