A pointing and signaling device for controlling the positioning, movement and operation of a cursor on a display screen that has a single piezoelectric element to indicate movement in three axes. The device generates electrical signals in response to a users force or actuation. The device has an actuator attached to a base. A piezoelectric element is mounted between the actuator and the base for generating electrical signals representative of a magnitude and direction of force applied to the actuator. The piezoelectric element is a shaped as a hollow cylinder. The piezoelectric element includes several conductive traces located on an outer surface of the element and a ground plate located on the inner surface of the element. The conductive plates and the ground plate are connected to a flexible cable by solder.
