Abstract: A contact spring clip for a cartridge fuse blown fuse light indicator wherein the spring clip is manually squeezable for the installation and removal of the clip on the barrel of a cartridge fuse. The spring clip is provided with a track for holding an electrical contact assembly connected to the ferrules of the cartridge and which can either be connected to a blown fuse light indicator positioned at a location remote from the fuse, or connected to a blown fuse light indicator mounted on the electrical contact assembly.

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.

Abstract: An EMI/RFI shield cap assembly retrofitted to standard military and/or commercial, panel mounted, indicating and non-indicating fuse holders.
