Abstract: This invention is directed to a lampholder for receiving a non-incandescent lamp having a 2-pin base. A surface mountable member for receiving the lamp and which has no voltage transforming circuitry is disclosed. Each pin of the lamp has an enlarged cylindrical shaped end attached to a shaft of reduced diameter. The surface mountable member has two keyhole shaped apertures, each of which has a large circular end aperture and an arc shaped slot for receiving and securely holding the pins of the lamp to the surface mountable member. The circular aperture of each keyhole shaped aperture has a diameter which is slightly larger than the diameter of the enlarged cylindrical end of the lamp pin, and the arc shaped slot has a width that is both smaller than the diameter of the cylindrical end of the lamp pin and wider than the diameter of the shaft of the pin. The enlarged ends of the pins of the lamp, when located in the arc shaped slots, prevent the lamp from being pulled out of the surface mountable member.

Abstract: An indexing mechanism with positive ON and OFF positions for a motor starter switch mounted in an NEMA 3R enclosure. The indexing mechanism includes a shaft having longitudinally extending projections coupled in fixed relationship to a handle, an index element coupled to the shaft, and a yoke having a pin positioned to engage the index element to positively position the shaft to the first or the second position.

Abstract: A wiring device common in household circuits includes a flexible brush that is a separate piece from a screw plate that receives electrical power. A terminal screw can thread into the screw plate. The brush may be positioned between the screw plate and the head of the terminal screw and can have a clearance hole through which the threads if the terminal screw can pass. Good electrical and thermal conductivity is assured between the screw plate and the brush by tightening the screw. A ground strap can be employed to hold a cover to a base of the electrical device. The strap can include openings which engage snap tabs on the cover to lock all components into a complete assembly. The strap also can have hooks which engage the cover to prevent the cover from being pulled out of the strap. The wiring device can be an electrical switch, a receptacle, or any similar type of device.

Abstract: A clip member which, when fastened to a lampholder such as, for example, a G8.5 lampholder, helps to position a lamp to be in alignment with the lampholder and with an associated luminaire. The edges of the recess of the lampholder for receiving the lamp are chamfered to facilitate insertion of a lamp into the lampholder. Proper alignment of a single-ended bi-pin lamp such as a G8.5 lamp is critical to ensure that there is an even distribution of light in all directions when the lamp is energized. The clip member contacts an end of a lamp installed in the lampholder and, together with the spring tabs on the clip, urges a lamp installed in the lampholder to its upright position and, in addition, helps to stabilize it.

Abstract: A lamp holder having oval contact openings to enable an installer to quickly and easily align and insert two contact pins of a single end lamp into the oval contact openings. To further facilitate the insertion of the round contact pins of the lamp into the lamp holder, the oval contact openings have ends which are chamfered. To further facilitate the alignment and insertion of the pins into the contact openings, the long axes of the oval openings are aligned and lie on a common axis. In addition, the lamp holder supports at least two bushings which holds the front and back portions of the lamp holder together and can be used to facilitate the mounting of the lamp holder to a luminaire.

Abstract: An electrical switch device adapted to be secured to an electrical outlet box mounted behind a wall member, having elongated, non-metallic mounting straps formed integrally with the device cover, and an improved grounding system adapted to automatically ground a metallic wall plate intended for use with the device without using the usual metal mounting strap. The mounting straps are proportioned to the maximum possible dimensions to fit under the wall plate to abut the wall member so as to substantially reduce the chance of a floating installation. Grounding means affixed to the cover adjacent one of the mounting screw apertures is adapted to engage a mounting screw inserted through the aperture so as to provide good electrical communication therebetween.

Abstract: A unitary switch and circuit breaker (10) includes a switch circuit (14, 16, 22, 24, 26, 56, 57, 58) with first and second contacts (28, 30), the switch circuit (14, 16, 22, 24, 26, 56, 57, 58) being actuable to assume a first condition (FIG. 4) in which the contacts (28, 30) are open and a second condition (FIG. 5) in which the contacts (28, 30) are closed, and a circuit breaker (24, 26, 32, 42, 56, 57) integrally formed with the switch circuit (14, 16, 22, 24, 26, 56, 57, 58) for actuating the contacts (28, 30) to interrupt current flow through the contacts (28, 30) in response to the current flow exceeding a predetermined level and for subsequently preventing the resumption of current flow through the contacts (28, 30) until reset.
