ABSTRACT:
A trackball system is provided wherein a roller ball is received and supported within a ball retaining assembly. A vertical height of the ball is adjusted relative to the housing by adjusting a vertical height of the ball assembly relative to the housing. By changing vertical height of the ball relative to a top surface of the housing having an aperture through which the ball protrudes, a selectable portion of the ball will protrude through the aperture. Thus, an operator may make height adjustments of the ball relative to the top housing surface to suit his individual preference.
