This is a joystick very similar to the "analog" joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down.
Hobbyists can get it installed on their own developed PC board for mounting and wiring or simply use our supplied finished breakout.
