Fuse box, particularly for motor vehicles

摘要

Fuse boxes for motor vehicles, in which fuse elements are carried on a support plate mounted on a box containing a light source. Each fuse element has a region of small cross-section overlying a respective one of a plurality of apertures in the support plate. When the small cross-section region of a fuse element melts the underlying aperture is exposed. Light from the light source passes out through said aperture to illuminate a circuit symbol adjacent the support plate thereby giving a visible indication of fuse element failure.
