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 housing member (14) to accept the ends of shaped conductors (92,94) to correctly position them with respect to their terminals (86,88).

Turn knob lampholder

A lighting fixture composed of a lampholder which can receive an electrical lamp and supply to it AC power and a body member into which the lampholder can be placed for support and protection. A locking member in the form of a flat, resilient metallic band with end portions bent at an acute angle provides a one-way clutch which permits the lampholder to be placed into the body member but prevents its withdrawal. Channels in the interior wall of the body receive the band ends to prevent rotation of the lampholder. The channels are employed in pairs and a single pair or two pairs at right angles to each other are employed.

Push-in lampholder mounting system

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.

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).

Lockable mount for an electric lamp socket

Tool for disengaging portions of a lamp socket

Combined anti-rotational bracket and snap-in clip

The present invention teaches a lockable lampholder mounting system wherein a housing containing electrical contacts, such as an electrical wiring device of the type exemplified by an incandescent lampholder or socket, is removably mounted upon a preselected panel by means of a novel clip arrangement. The panel is of the type utilized in a fixture, for example. The clip arrangement includes a resilient clip of predetermined shape formed with at least three bearing surfaces for contacting the panel, and preferably a fourth bearing surface against which a locking tab is biased to prevent rotation and relatively upward movement of the wiring device.
