I am doing a school project, and need to know how a mechanical mouse operates (not how to use it, how it works). Please try to explain and put a link so I can get the information i need. Only put popular websites, not including Wikipedia.

Boots is pretty close.
The ball in the mouse, as it moves, turns two bars -- one for the X axis movement and one for the Y axis movement.
Attached to those bars are wheels with slits in them. There's a light/light sensor for each wheel. As you move the mouse, the wheels turn, and the sensors get to count the transitions from dark to light.
The mouse sends the counts to the computer through a standard serial interface, or some other communication interface (these days, USB is common). The raw counts are called "mickeys." Your computer's mouse driver decides how far and in which direction you've moved the mouse based on the mickeys received. It then uses a "mickeys to pixels" formula, as well as an acceleration formula, to determine how far to move the mouse pointer on your screen.

I have no links, but first it needs power, and then that power needs to be channeled to a motor which would then runs the gears to make the movements happen. Honestly I have no clue. But it sounds logical. Good luck though.

A "roller-ball" underneath contacts rollers attached to gears that electrically translate as motion...up,down,left,right,
