DEFINITION

Classification: 337/46

(under subclass 45) Subject matter including a single means whereby the plurality of phase or leg contact pairs are simultaneously actuated to or from a closed circuit condition or maintained in a first position until released whereupon the plurality of contact pairs are allowed to move to another condition simultaneously.
