A lamp socket and bulb assembly includes a socket having a generally rectangularly configured bulb opening and first and second side contacts to stabilize a bulb base against multiplanar reference walls in the socket; and wherein the base includes bulb filament contacts, spaced apart parallel reference surfaces and a pressure pad thereon all axially insertable into the socket to make electrical contact between the first and second side contacts and the bulb filament contacts, having a segment that exerts a force on the pressure pad to locate the parallel reference surfaces against one side wall of the socket and a curvilinear segment that engages an outwardly directed tab on the base to stabilize the base within the bulb opening by exerting a pull-in force thereagainst.

A combination lamp socket and base assembly for use with a lamp having a bulb with a filament therein requiring alignment in a precise relationship to optical components of a lamp assembly comprising: a bulb base of polyhedron cross-section including a plurality of axially spaced parallel reference surfaces on one side of said base to define a three point reference platform thereon, a reference stop surface on said base formed transversely of said parallel surfaces, a pair of electrical contacts supported exteriorly of said base extending axially thereof, each contact being electrically connected to the bulb filament for supplying power thereacross, a lamp socket having means thereon for removably securing said socket to a panel at a socket opening therein, wall means in said socket defining a bulb base opening for axial insertion of said lamp base into said lamp socket, said wall means including a side wall surface having a first portion extending axially of and in parallelism to the longitudinal axis of said bulb base opening, said side wall surface including a second portion defining an insert stop surface engaged with said reference stop surface to limit axial insertion of said bulb base into said recess, said plurality of parallel reference surfaces located in juxtaposed alignment with said side wall surface to position the bulb filament along a first axis, said reference stop surface being in juxtaposed relationship with said second portion of said side wall surface to position the bulb filament along a second axis, a first electrical contact terminal including an axially extending support secured to said wall means, a curvilinear contact segment on said first contact terminal formed reversely of said support and dispOsed within said bulb base opening to engage the bulb base to apply a first resultant axial force thereon to pull said bulb base axially inwardly of said bulb base opening to stabilize the bulb filament along the first axis and to electrically mate with one contact of said pair of electrical contacts on said bulb base, a pressure spring on said first electrical contact terminal extending inwardly of said bulb base opening to engage another side of said bulb base to produce a second resultant force thereon generally transversely of said bulb base to bias the three point reference platform thereon into engagement with said side wall surface to stabilize the bulb filament along the second axis, and a second electrical contact terminal supported within said wall means including a contact segment thereon biased toward said bulb base into electrical contact with the other one of said pair of electrical contacts on said bulb base.
