ABSTRACT OF THE DISCLOSURE An electric fuse is provided with a blown fuse indicator mounted on a lateral wall of the fuse. One of the end terminals of the fuse is provided with a first opening therein in a surface which faces the interior of the fuse casing. The same end terminal is provided with a second opening therein which is in a peripheral surface of the terminal and which lies in a plane which is substantially parallel to the longitudinal axis of the fuse casing. The end terminal is further provided with an internal passageway therein which communicates the first and second openings. The fuse casing is provided with an opening therein which is in axial alignment with the second opening in the end terminal. A spring loaded blown fuse indicator is mounted through the opening in the fuse casing and is fixedly and conduc- tively engaged with at least a portion of the end terminal pass- ageway. An indicator restraining wire has one end attached to the spring loaded indicator and extends along a path comprising at least a portion of the passageway to the interior of the fuse and from there along the full length of the fuse to the other end terminal. The restraining wire is stretched taut along its described path and is conductively attached to the other end terminal.
