TURN KNOB LAMPHOLDER

摘要

A lampholder includes a three way, two circuit switch for operating a two filament lamp. The lampholder has a single socket housing with the switch mechanism incorporated. It has mating top and bottom housings and an access door hinged to the top housing with raised ribs thereon which, when the door is closed, function to facilitate the displacement of insulation from wire inserted by threaded or unthreaded pipes into the bottom housing thereon by mating of the raised ribs with toothed protrusions on the access door. The housing is constructed to allow its outside surface to accommodate a great variety of designs. Also contemplated are a lampholder with a single circuit switch for operating a single filament lamp, as well as a lampholder without a switch for operating a single filament lamp from a remote switch.
