Abstract: A tri-dimming push handle switch lamp holder is disclosed, which enables a user to press the push handle for a selection among three dimming levels: full brightness, middle luminance and complete darkness, where the lamp holder is made up of a body, a first conducting member, a first contact plate, a conducting plate, a second conducting member, a second contact plate, a rectifying diode, a flap, a push handle, an insulating plate and a threaded tube shell, which are integrated together to form an advanced lamp holder that features not only the basic switching function but an extra tri-level dimming function, substantially boosting its usage for all kinds of occasions. Moreover, an extra arrangement of the conducting plate and the rectifying diode enables the structural combination and the function of this invention to present great creativeness.

Abstract: A light for use in a string of lights has a lamp and a light socket that may include a parallel group device that may perform a variety of functions. One of those functions is to serve as a resistive element to regulate voltage and current to keep other lights in a group of lights arranged to be electrically in parallel lighted to the same intensity in the event one of the lights burns out or is removed. Another function of the parallel group device is to control the lamp in the socket so that it lights and goes out on command. The socket is designed to be closed against moisture and to be easily manufactured by hand or by machine. It includes piercing terminals that, when pressed into the electrical wires that run from light to light in the string, allow electrical connection with the lamp leads and the parallel group device leads.

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.

Abstract: A convertible light fixture (10) capable of selectively functioning as a spotlight or floodlight. A preferred light fixture (10) includes a ground stake (12) supporting a bulb/lens assembly (14). An electrical cable (16), protected by the preferred S-shaped ground stake (12), makes contact with the bulb/lens assembly (14) at the rear thereof. More specifically, a pair of prongs (60), which also support a bulb (62), protrude from the rear of bulb/lens assembly (14) and make contact with electrical cable (16). Preferred bulb/lens assembly (14) includes a stationary housing (40) and a rotatable focus ring (70) wherein rotation of the latter relative to the former causes axial movement of a reflector (80) relative to bulb (62) to change the degree of focus of the light beam produced by fixture (10). Another feature of preferred bulb/lens assembly (14) is a lens (90) which produces a rectangular light beam adjustable in orientation.

Abstract: An electrical connector includes stab portions and a cam for urging a wire cord into contact therewith. The cam mounts in a tubular housing which is telescopically receivable in a sleeve. The cam and housing coact such that the cam head tends to move outwardly from the housing when the cam is moved to a position to release the wire cord, and this is prevented by the sleeve. As a corollary, if the cam is turned away from its wire locking position, the housing cannot be engaged with the sleeve. The sleeve acts as a conduit for the wire cord, whereby the cord tends to anchor the housing in telescoped position in the sleeve, to prevent unauthorized tampering with the connector.
