Abstract: The present invention relates to a plug with an integral fuse which is to be inserted into a conventional outlet of a power supply, e.g., an A.C. outlet having openings to accept the two plug's two terminals. It has heretofore been known to provide plugs of this type with a fuse connected in series with one of the lead wires and the corresponding plug terminal which is to be inserted into the outlet. Such fused plugs usually comprise a housing with a replaceable cartridge type fuse therein which is held between a generally U-shaped pair of spring contacts. The housing can be opened to replace the fuse if it blows.

Abstract: A lamp socket is provided with a body member or shell having an opening in its top and first and second electrical contacts in the shell to make electrical contact with a light bulb inserted into the shell. A tapered, resilient support arm projects inwards from a wall of the shell to engage the bottom face of an inwardly projecting tab portion of one electrical contact, which engages the base of the light bulb. This resilient arm prevents permanent deformation of the tab upon insertion of a light bulb to a greater than average depth into the socket and returns the tab to its initial position after the light bulb is removed. The other contact engages the light bulb ferrule.
