摘要： A dead front electrical blown fuse indicator for all standard cartridge enclosed fuses of both the ferrule and knife-blade types each comprising a casing or tube molded from insulating materials having an indicator lamp and contact terminal connected in series encased within the tube and said tube being opaque as to prevent the lamp and its electrical connections from being visible and yet being sufficiently translucent as to permit the lamp to glow over a wide area so as to be visible at all angles and at great distances from the tube. Resilient conductors electrically connected to said terminal for the lamp and each having a cantilever connection with the tube for causing the free ends of said resilient conductors to have a direct and positive snap-on electrical contact with the outer walls of the terminals of a fuse even when the fuse is subjected to undue vibration or shock. Said tube having sufficient tensile strength so as to prevent the bending or breakage of the tube due to its repeated application to and withdrawals from a fuse.
