A key operated switch that provides enhanced operational characteristics wherein the rotary motion of a key is translated into the actuation of a switch mechanism that rapidly establishes an electrical connection between a source of electrical current and a load. The switch uses a toggle adapted to interact with a standard switching mechanism which reduces the number of components and the cost of the switch. The key cylinder is coupled to a yieldable member such as spring to provide a positive or snap action when the key cylinder is rotated with a prescribed arc of rotation which reduces the complexity of the switch.

Key operated security switch

A lamp housing to support and power a compact dual or quad-tube fluorescent lamp. A body portion with a central cavity receives the lamp base and selectively retains same using a trapped metal clip; contacts mounted in separated cavities receive the lamp leads at a first end and at the second end the bared end of an electrical conductor inserted into a one way type clutch contact lever to apply AC power to the lampleads. The contact lever can be bifurcated to independently engage more than a single conductor. The lamphousing can be mounted to a panel using fasteners extending through apertures in mounting pads of the base, or by using flexible mounting tabs to grip the underside of a mounting panel or a combination of the flexible mounting tabs and flexible arms to permit the lampholder to be mounted on panels of different thicknesses.

Lampholder for compact fluorescent lamps

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).

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 (93,95) 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, 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).
