Abstract: A computer command and pointing device that attaches directly to the computer or keyboard without the need for external electrical cables. A BallPoint.TM. mouse has a multi-axis mechanical engagement assembly that allows the mouse to be inserted into a recess in the computer or keyboard and have its weight fully supported by the engagement assembly. The engagement assembly provides tight mechanical coupling between the mouse and the recess, but permits the disconnection of the mouse if excessive force is applied to the mouse. The engagement assembly includes an electrical connector that permits the coupling of electrical signals between the mouse and the computer. The connector pins in the electrical connector are individually spring-loaded to allow the connector pins to recede into the electrical connector when force is applied. A mating electrical connector plate, mounted within the recess, is a flat plate made of an insulating material with electrically conductive pads on the surface thereof.
