Fuse box, particularly for motor vehicles
First Claim
1. A fuse box for a motor vehicle providing an illuminated indication of a melted fuse comprisinga support plate mounted on the vehicle, a plurality of apertures through the support plate,illumination means on a first side of the plate for providing light to the apertures,a plurality of meltable fuse elements on the plate, the fuse elements normally covering each of the apertures respectively to block the light through the apertures, whereby a lighted aperture is exposed when its corresponding fuse element melts to provide at the second side of the plate an illuminated indication of the fuse melted condition.

Abstract
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.

3. A fuse box for a motor vehicle for providing an illuminated indication of a melted fuse comprising
a support plate mounted on the instrument panel of the vehicle, a plurality of apertures through the support plate, illumination means on a first side of the plate for providing light to the apertures, a plurality of meltable fuse elements on the plate, each fuse element being a part of a vehicle circuit, the fuse elements normally covering each of the apertures respectively to block the light through the apertures, a translucent cover plate disposed over the second side of the support plate and symbols on the cover plate aligned with the fuse elements and identifying the circuit of each fuse element, whereby a lighted aperture is exposed and a symbol on the cover plate is illuminated when its corresponding fuse element melts to provide an illuminated indication of the fuse melted condition.
