Abstract
A blown fuse indicator for a cartridge fuse wherein conductive brackets are mounted between electrical insulating end caps and the ends of a tube housing a lamp and associated resistors. Each conductive bracket includes a disc portion having a polygonal aperture for receiving a sleeve integral with the cap, the sleeve having a polygonal cross-sectional configuration corresponding to the disc aperture. The free ends of the lamp and resistor leads extend through the disc portion of the conductive bracket and are pressed and gripped between the cap and conductive bracket. The conductive bracket also includes a blade portion which may have a planar surface, a corrugated surface or a reversely bent portion to provide direct and positive contact with the end walls of the fuse ferrules, whether they be flat, concave or convex.
