Blown fuse indicator circuit and fuse cap, including a method of use therefore

摘要

The present invention is substantially an indicator cap which is removably attachable to a prior art plug-in type fuse, and the cap having an indicator light for signaling that a fuse has blown so as to notify a user of the blown condition of the fuse. Furthermore, we provide unique circuitry which in combination with the existing circuitry provides unusual results, and we also provide a method of use therefore.
