ABSTRACT:
A circuit fuse assembly comprising a plurality of fuse elements which are simultaneously formed using printed circuit or through hole plating techniques and including means for easily substituting a different one of the plural fuse elements when the in-circuit fuse element burns out due to an overload current condition. In the preferred embodiment, the fuse assembly is (a) integrally formed with the printed circuit of the fused electrical apparatus and (b) formed with a common electrical connection such that a single electrical bridge of solder or other means enables substitution of a replacement fuse element. Other embodiments of the present invention provide a restorable printed circuit fuse for use in standard fuse holders, in-line plug connectors, conventional three prong plug connectors, edison bases, and plug-in triple outlets.
