Abstract
An electronic device, for example a handheld telephone, having an integrated joystick with a conductive contact surface disposed toward a printed circuit board (PCB). The joystick is aligned with a neutral position contact portion of the PCB when the joystick is in a neutral position. A joystick contact region of the PCB has a plurality of directional contacts disposed circumferentially around the neutral position portion, corresponding to different joystick input directions. The conductive portion of the joystick electrically interconnects a ground contact with a corresponding one of the directional switch contacts when the joystick is pivoted in a corresponding input direction.
