DEFINITION

Classification: 337/64

(under subclass 62) Subject matter wherein the mechanical contact controlling structure includes camming or wedging means whereby a force is transmitted from a driver element to a driven element through the principle of friction in such a manner that the contacts are positioned from a first or operated condition to a second nonoperated condition as a direct result of the frictional force generated.
