Abstract
A device for detecting whether any of a plurality of fuses has blown out. The fuses are connected between a first terminal of an electrical source and a number of loads, the loads also being connected to the other terminal of the source. The device comprises one light emitting element for each fuse. One end of the light emitting element is connected to a junction between the fuse and its load. The other ends of the light emitting elements are all connected together to one terminal of a switch, having another terminal connected to the other terminal of the electrical source. When the switch is closed, the light emitting element corresponding to any fuse which has blown out is not lit.
