Mechanical mouse
Updated: 04/12/2021 by Computer Hope
A mechanical mouse is a computer mouse containing a metal or rubber ball on its under side. When the ball is rolled in any direction, sensors inside the mouse detect the motion and move the on-screen mouse pointer accordingly. The picture shows the bottom of a mechanical mouse with the ball removed. Today, this mouse has been replaced by the optical mouse. A mechanical mouse is susceptible to dust particles and other debris getting on the ball and preventing the mouse from working.
