DEFINITION

Classification: 337/45

(under subclass 41) Subject matter comprising a plurality of individual conductors with contact pairs associated with each conductor, a contact actuating means for each contact actuating means for each contact pair, each contact pair completing a circuit through one branch of a polyphase or plural conductor electrical circuit. Devices which are known as bipole or double pole and which complete the circuit in each conductor of a direct current circuit will also be found here.
