Abstract
A fuse indicator is disclosed for indicating the status of a fuse. The fuse indicator includes an electrically conductive material that extends between conductive ends of a fuse and undergoes a visible change in appearance upon being subjected to electrical current above a threshold. The fuse indicator also includes a layer of indicator material that becomes exposed beneath the electrically conductive material when the fuse indicator is subjected to electrical current above the threshold. The fuse indicator also includes adhesive for maintaining contact between the electrically conductive material and the layer of indicator material.
