A narrow strip of metal-clad material, as used in printed circuitry, is placed inside the casing of a fuse taking the place of the fusible conductor or element. The metal layer is, in part, removed from the strip by etching, or otherwise, leaving a central zone which is completely bare and two axially outer zones where the metal layer is substantially I-shaped. The axially inner ends of this I-shaped metal overlay are conductively interconnected by a spring-biased shorting strip which shorts said completely bare zone. The shorting strip is attached by soft solder to the axially inner ends of the I-shaped overlays and is spring-biased to a circuit interrupting position. The axially outer ends of the I-shaped overlays are connected by blind solder joints to terminal caps mounted on the ends of the casing of the fuse.
