. To assemblethe socket, the lighting elements 36 with.

the wires 38 permanentlyattached thereto is inserted into the open 'en'dl34 so that the wires protrude out of the apertured'base 30. The glass lensl44 is snapped into engagement with the recess 42. The socket assembly is then'snapped into the semicircular-opening 16, thereby "x'jengaging the support panel 18. by'pressing the resilient In many types of electrical stoves, a housing forming.

has been experienced in the retention of lamp sockets o'f the. push-in type due to the thinness, of these panels with the resulting misalignment of cover panels.

A primary object of this invention is the provisionof a lamp socket assembly adapted for sideways insertion into a semi-circular aperture formed in the housing.

Another object of this invention is toprovide a one piece lamp socket which may be molded integral with the attaching elements. I

A further object of this invention is to provide a lamp socket of improved and simplified construction having a semi-circularopening 16, resulting in the collar 24con- -tracting inwardly toward the recess 39. The -,edges 14 I at the semi-circular opening 16 comprise an are of lesser diameter thanthe diameter of the collar 24 as shownfin' Fig. 4, while the diameter of the aperture isof asizeto retain the collar 24 s'etm'relyin position as -shown Fig. 3."

During t hejassembly'operation, the collar 24'is compressed by the, edges 14fat the aperture 16 until it has passed: therethrough and has-cleared the edges thereof at whichlt im'e it snaps outwardly within the" main body of the opening 16. In thisjposition,"'the shoulder portion 7 abuts the outer face of the support 18 and together one piece housing formed of a semi-resilient material which may be assembled with the lighting elements prior to insertion into a support.

Other objects of this invention'will, inpart, be obvious, 1"
