Notebook Mouse 3000: Top cover bottom viewHere's a view inside the bottom of the mouse's top cover. You can see the barrel plastic designed to hold the AA battery to the bottom right. At the top center is the cutout to accomodate the mouse's scroll wheel.
Also at the top are two somewhat square cutouts. Those accept the plastic tabs from the left and right click buttons and enable clicks to be transmitted as electrical signals to the device's circuit board.
