ABSTRACT:
A spring loaded blown fuse indicator is provided that is adapted to be mounted directly on the side of an electric fuse in parallel with the fuse current path.
The indicator provides an indicating pin that extends perpendicular to the longitudinal axis of the fuse. The indicator body comprises two identical molded halves which facilitate assembly and allow the indicator restraining wire to be readily encapsulated in an arc-quenching epoxy adhesive.
