Turn knob lampholder

Abstract

A unitary lampholder (10) including a lamp socket (12,14) as well as a multi-position switch which can take the form of a three-way, two circuit switch for operating a two filament lamp, a single circuit switch for operating a single filament lamp or arranged to permit the switch to be operated from a remote point. The lampholder has a bottom housing (14) and a top housing (12) which includes an access door (16) which is slidably and rotatably mounted to the remainder of the top housing by a guide member 54 which moves within slots (93,94) and permits the access door 16 to be rotated from a position on and perpendicular to the top housing axis to one parallel to that axis in which position it can be slidably moved towards the bottom housing. Upon slidably moving the access door towards the bottom housing, projections (160, 162) on the base of access door force insulated conductors (92,94) into the insulation displacing terminals (86,88) of the contacts (60,62) to make electrical contact therewith. Other projections (154,156) securely grip the conductors to provide strain relief. A square aperture (194) and a round aperture (196) can be placed in bottom housing member (14) to accept the ends of shaped conductors (92, 94) to correctly position them with respect to their terminals (86, 88).
