A mechanical input to electrical output device such as a touch pad module for controlling the movement of a cursor comprising two movable plates attached to a fixed plate and a scanning device. The tracks on the top and bottom of the middle movable plate allows for an "X" axis movement of the top plate and an "Y" axis movement of the middle plate that slides on the fixed plate. This combination allows the scanning device to read the movement of the top plate through a slot (cut-out) on the fixed plate and a slot (cut-out) on the middle moveable plate from underneath all three plates. Consequently, the scanning device is able to track or read the movement or position of the top plate in two dimensions.
