Abstract
Abstract Electrical socket device includes a socket housing containing a center contact assembly having a resiliently mounted freely movable center contact to enable a lamp mounted in the socket to be correctly positioned in axial alignment in the socket while providing good electrical contact. Spaced ledges are provided in the socket housing on opposite sides of the center contact assembly for engaging the lamp base to maintain proper alignment of the lamp.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
An electrical socket comprising, in combination, a socket housing having an open end and a transverse base portion near its other end and having a central axis, said housing base portion having a pair of spaced slots extending therethrough on opposite sides of said central axis, resilient means arranged on said housing base portion between said slots, and U-shaped conductive contact means having a pair of legs respectively extending loosely through said slots and having a web portion engaging said resilient means, said legs having electrical terminal means for making an electrical connection to said contact means, and securing means movably holding said contact means on said housing base portion with said web portion pressed in yieldable engagement against said resilient means, said contact means being freely movable in all directions to accommodate the position of an electrical device adapted to be received in said socket housing in engagement with said contact means.
