Abstract

Electronic equipment control of a parameter of electronic equipment includes magnetic encoder responsive to magnetic input to provide control output for electronic equipment, a connector member connects electrically with a further connector member; the magnetic encoder receives magnetic input representing relative motion between the further connector member and the connector member to provide such control output. The further connector member has an electrical terminal connectible with the connector member, a magnet positioned relative to the electrical terminal for movement therewith providing magnetic output representing such movement, and the magnet and magnetic encoder are in proximity for magnetic coupling to provide the magnetic encoder magnetic force representing relative movement of the connector member and further connector member. A method of adjusting a parameter of electronic equipment includes effecting relative movement between connected parts of an electrical connector, and using magnetic force representation of such relative movement adjusting such parameter.
