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.
