ABSTRACT:
A multi-dimensional computer mouse includes a casing in which a circuit board is mounted. Left and right buttons are provided on a top of the casing for functioning as regular mouse push buttons. A third push button is arranged between the left and right buttons. A post extends from the third button to the circuit board. A spherical expansion is formed on a lower end of the post and rotatably received in a socket fixed on the circuit board for forming a joint allowing the post to be rotated from a neutral position to front and rear actuation positions wherein a collar of the post contacts and triggers a front contact switch and a rear contact switch. The post is floatingly supported by a spring arranged between the socket and the collar thereby allowing the post to be depressed against the spring for having the lower end of the post contact and trigger a bottom contact switch. Thus, a user is allowed to selectively trigger either one of the three contact switches for controlling a monitor cursor of a computer to which the mouse is coupled.
