DEFINITION

Classification: 337/143

(under subclass 142) Subject matter comprising manual or other mechanical means acting conjointly or cooperatively with, at least one fusible element, or which acts as an intermediary between the fusible element and at least one movable contact thereby opening or closing an electrical circuit. The manual or mechanical means may act independently of the fuse device as long as they are each in the same circuit and the circuit is completed when both are in the circuit closing position. For example the combination may include a blade switch in series with a cartridge fuse.

(1) Note. For other manual or mechanical switch control means used in devices of this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 115.
