Abstract: A control switch with a holder is to be provided which can simply and quickly be secured by one person to a variable-thickness fitting plate. To this end the rose (9) of the control switch has a longitudinal groove (11) and a transverse groove (12). The holder which can be fitted on the rose (9) consists of a lower casing (14), a securing ring (5) and an upper casing (23). The lower casing (14) and the securing ring (5) have matching pitches (20, 6) so that when the securing ring (5) is rotated via a toothed spindle (7) fitted off-center it is axially shifted. After the holder has been fitted on the rose, when the securing ring (5) is rotated, a partial thread (18) fitted thereto is rotated out of the longitudinal groove (11) into the transverse groove (12) and thus pressed by the simultaneous axial movement of the partial thread (18) against the limiting edge of the transverse groove (12) taking the form of a thread segment (13).

Abstract: A modular power distribution system is ideally suited for use in modular buildings of the type in which prefabricated building modules are constructed at a manufacturing factory and shipped to a remote building site where the modules are interconnected to form the complete structure. The modular power distribution system includes a primary power distribution panel positioned in one of the building modules and is adapted to distribute power from the utility service to the building modules. Modular power distribution units positioned in each of the building modules are adapted to distribute power within a respective building module. The primary power distribution panel has a plurality of main circuit breakers, each of which is electrically connected between the utility service and one of the modular power distribution units for limiting the maximum current through a respective modular power distribution unit.

Abstract: An audio I/O connector, a flex cable, an audio I/O extension card, a mounting bracket, and a besel, designed to couple and complement each other in a particular geometrical manner, are provided to conduct I/O of audio signals at the front panel area of a Baby-AT/LPX and the like system unit previously sealing the hard drive bay. The audio I/O connector reorients an otherwise conventional audio add-in/adapter card to conduct I/O of audio signals through the frontal portion of the Baby-AT/LPX and the like system unit. The flex cable transports the audio I/O signals to and from the front and back portions of the Baby-AT/LPX and the like system unit. The audio I/O extension card facilities conduct of audio I/O with external audio devices at the front panel, the aforementioned area in particular. The mounting bracket secures the audio I/O extension card to the hard drive bay. The besel exposes audio I/O ports of the audio I/O extension card at the front panel area of interest.

Abstract: A fully automated circuit breaker saddle assembly in the form of a plastic support base having modular components that define the end and central sections of the support base. The components are snappingly fitted together and are retained by means of formations on the ends of the respective components. The metal circuit breaker stab assemblies are attached to the base by connectors integrally-formed in the base.

Abstract: A power distribution box is provided with built in surge suppression capabilities that can be service without interrupting power to downline circuits powered from the power distribution box. A socket is wired directly to the busses supplying power to the circuit breakers in the power distribution box. The socket is designed to accept a surge suppression module that can be removed and replaced while the electrical connections in the socket are "hot." To prevent accidental electrocution the electrical contacts of the socket are place below the surface of the socket. Additionally, the stab-in connectors of the socket and the corresponding stabs of the surge suppression module are arranged in such a way as to ensure that the module is properly polarized when inserted into the socket.

Abstract: A method of producing a molded assembly for at least partially encapsulating a touch panel structure. The method includes providing a touch panel structure which has a front side, a reverse side and an edge extending therebetween. A circuit is attached to the panel structure and includes at least one device. The panel is positioned in a cavity of a plastic injection mold which includes a hollow shutoff positioned relative to the device on the touch panel. When the mold is closed, a rim portion of the hollow shutoff is positioned against the reverse side of the panel spaced away from the device so as to at least partially shield the portion of the panel containing the device from the injection molding environment. The present invention also envisions a product produced by this method.

Abstract: An electrical loadcenter bus bar mounting assembly which has a plurality of juxtaposed synthetic plastics moulded members. Each member is formed to interlock with each next adjacent member and has a plurality of location lugs for engagement with apertures in a support member.

Abstract: In a power board, network transformers are disposed horizontally to reduce their height, network buses are disposed above the network transformers and a protector breaker and take-off breakers are disposed at the front of the power board in electric chambers and connected to the network buses. This arrangement places the two types of breakers and the electric chambers within the range of height accessible by an operator's hand to permit him to manually handle these breakers, thereby improving ease of handling of the power board.

Abstract: A local area network including cabling interconnecting a plurality of workstations, the cabling including a plurality of data ports and conductors for selectable and removable interconnection between selected ones of the data ports and apparatus for automatically providing an indication of the connection pattern of the data ports.

Abstract: An interlock between two main circuit breakers comprises a bracket mounted to the interior panel transversely of the panel and a sliding interlock member mounted on a forward portion of the bracket, which portion fits within the unmodified opening of a panelboard cover and fills the space within the opening between the two main circuit breakers. Padlock hasps may be provided on the interlock member to additionally lock either or both main circuit breakers in an OFF condition. Tabs on the bracket overlie forward facing surfaces of the main circuit breakers to block removal of the main circuit breakers while the bracket is installed.

Abstract: A safety retainer for retaining an electrical device connected to an electrical receptacle against inadvertent disconnection includes a cover plate having opposed raised bars secured to the cover plate adjacent the electrical connector of the receptacle and a retainer strap looped beneath the raised bars and across the electrical device to secure the electrical device in place when connected to the receptacle, the cover plate being unbroken between the electrical connector and the peripheral edge of the cover plate so as to provide a completely integrated cover plate over the receptacle.

Abstract: A car stereo has a grille detachably mounted on a stereo body. Engaging recesses are formed at the four corners of the grille. Flexible latch members are provided on the stereo body, each of which is adapted to engage with the corresponding engaging recess of the grille when the grille is attached to the body. A release mechanism is provided on the body, which is operated by a release member provided on the grille. When the release mechanism is operated, the engagement between the engaging recesses and the latch members is released.
