Blown fuse indicator.

摘要

A blown fuse indicator is described which is adapted to be attached to the exterior of an electric fuse. A pair of spaced conductive terminals are attached to a rigid electrically insulating body and are adapted to attach the indicator to a fuse. The body has an indicator wire path extending between the terminals and an indicator restraining wire is tightly drawn along this path and electrically conductively connected to the terminals. A spring biased indicating means is carried by the body at a position along the path. The wire is substantially completely encapsulated by an arc quenching material except for a portion thereof which restrains the indicator against spring bias in a not blown condition. The wire fuses when the fuse blows releasing the indicator.
