Abstract

A pull chain outlet box lampholder which is assembled at the factory and does not require the mating of parts of dissimilar material in the field. A body member has a recess in its rear face to accept a switch assembly. A bore in the neck of the body member receives a threaded screwshell. Fasteners extend from the screwshell to the switch assembly to assemble these parts and to clamp an annular ring in the bore between them whereby the switch assembly and the screwshell are held in assembly to each other and to the body member.
