DEFINITION

Classification: 337/317

(under subclass 312) Subject matter wherein the contact control structure includes spring or other potential energy storage means whereby a major portion of the force used in actuating the contacts of the device. The actuating force is usually transmitted to the movable contact structure through mechanical means upon the spring being released from its energy storage position.
