Electrical volume control using contacts on rotatable connector, and method

摘要

Electronic equipment control of a parameter of electronic equipment includes contacts on relatively movable connectors to provide control output for the electronic equipment, a connector member connects electrically with a further connector member, and a direction decoder receives inputs from the contacts representing relative motion between the further connector member and the connector member to provide such control output. A method of adjusting a parameter of electronic equipment includes effecting relative movement between connected parts of an electrical connector, and using a number of contacts on the connected parts obtaining a representation of such relative movement adjusting such parameter.
