Abstract
A computer mouse used to control the monitor screen, having only two contacts (the minimum possible contacts). The spherical ball is in touch only with the coordinate shafts. The third contact, necessary for ball stability, is replaced with a magnet which will engage the ball with the coordinate shafts. The magnet will not touch the ball.
Claims1
A computer mouse having the rotatable ball with two contacts inside of it, comprising:
- a magnet which attracts the mouse magnetic core ball and rubber outer layer, without touching the ball, against the coordinates x and y shafts, in a plane parallel with the shafts x and y plane.
