What type of mouse has no mechanical parts?
Optical MouseAll mice have moving parts. There is no such thing as a computer mouse not having moving parts. And before you pop off (or mouth off or whatever you want to call it), the "buttons" that you use to "click" an icon or link and the scroll wheel of the mouse are moving parts. As a matter of fact, the entire mouse is a moving part. Unless it is a trackball mouse, in which case only the trackball and the buttons are the only moving parts.
