Abstract: A self-deactivating tethered interconnection system for a power outlet is provided, in which a circuit breaker actuates to selectively disable transfer of electrical power supplied at a source side of the power outlet to a load side thereof. A conductive tether disposed at the load side transmits the electrical power transferred by the circuit breaker. A power connector coupled to the conductive tether is configured for interconnection with a load for delivery thereto of the electrical power transmitted by the conductive tether. A proving circuit coupled to the power connector and circuit breaker includes a sensing portion that detects an interconnection state of the power connector to the load, and a trip portion operating responsive to the sensing portion to selectively inhibit transfer of the supplied electrical power to the load side. The power connector and conductive tether are thus adaptively de-energized when interconnection with the load is interrupted.

Abstract: A power socket device having switches is disclosed and has a housing, socket units, two conductive frames and switch units. The housing has bolt holes. Each of the socket units has a socket body and a pair of conductive terminals. The socket body is formed with a pair of terminal slots. The socket unit can be received in the housing, and slid upward and downward therein. The conductive terminals are inserted in the terminal slots, and selectively in contact with or disconnected from the conductive frames. The socket body has an engagement hole. The switch unit is inserted into the bolt hole, and selectively abutted against the socket body or engaged in the engagement hole, so that the socket unit can be positioned on a predetermined position on a vertical direction. Thus, it is unnecessary to unplug a plug of an external appliance when switching on or off the power.

Abstract: A group protection module for a switchgear arrangement is provided in order to protect a group of load feeders, each having a contactor for connecting or disconnecting a respective load. The group protection module has a circuit breaker for providing short-circuit protection, said circuit breaker being connected to a supply-side input and to a load-side output of the group protection module for connection to a power supply system and for connecting the group of load feeders. The group protection module has a safety evaluation unit via which the circuit breaker can be tripped if a status signal detectable by the respective load feeders indicates that one of the contactors of the load feeders can no longer be de-energized. The group protection module is implemented as a constructional unit.

Abstract: An improved electromechanical switch designed to operate at frequencies from DC through microwave has terminal probe tips that are formed from an alloy of noble metal and contoured with a pattern of peaks and valleys in order to provide better contact wiping operation and capture of wear debris. The switch incorporates damper elements to reduce switching contact bounce, thus providing increased contact life as well as higher quality signal switching.

Abstract: A sequential control master-slave socket device includes at least one master socket, a plurality of slave socket, a plurality of switches, a load judgment device and a controller. Each master socket is coupled to an input power source. Inlet terminals of the switches are coupled to the input power source commonly and outlet terminals of the switches are respectively correspondingly coupled with the slave sockets for controlling whether the input power source is provided for each of the slave sockets. The load judgment device is coupled with each master socket for outputting a control signal according to an electrify state of a load connected with each master socket. The controller is coupled with the load judgment device and each switch to drive the switches one by one in a preset sequence under the control of the control signal.

Abstract: A power strip device and a method for controlling the power strip device are provided. The power strip device is communicated with a host computer. A wireless signal emitter is connected the host computer for emitting a wireless signal. The power strip device has a wireless signal receiver for receiving the wireless signal. The power strip device of the present invention is controlled by detecting the wireless signal.

Abstract: An electromagnetic switch has a shaft and a movable contact member slidably supported by the shaft. The shaft is moved with a plunger when an electromagnet is formed of an electromagnetic coil receiving an electric current and attracts the plunger. The movable contact member is moved with the plunger and connects fixed contact members with each other to turn on the switch. The shaft has a shaft body and a projection projected from the shaft body. The movable contact member has a hole. The projection is inserted into the hole to pass through the hole, and the movable contact member is disposed on the shaft body. Then, the movable contact member is rotated so as to engage the projection with the movable contact member. Therefore, the projection prevents the movable contact member from coming out of the shaft.

Abstract: An enclosed switching apparatus includes an enclosure and a primary power supply disconnect mounted in the enclosure. The primary power supply disconnect has first and second terminals, the first terminals are electrically connectable to a primary power source and the second terminals are electrically connectable to a load. An auxiliary power supply unit includes an auxiliary power supply disconnect having third and fourth terminals. The third terminals are electrically connectable to the primary power source.

An auxiliary fusible element has seventh and eighth terminals, the seventh terminal is electrically connected to one of the sixth terminals of the transformer. A receptacle has ninth terminals thereon. One of the ninth terminals is electrically connected to the eighth terminal of the auxiliary fusible element.

Abstract: A switch box (named a security switch) comprises a housing with a manually and/or automatically activated ON/OFF switch for a phone and/or data line connected through the switch box. A user can disconnect his computer from the Internet to eliminate hacking when the computer is not in use. A simple push/pull lever moves any available type of male/female plug from a connect to a disconnect mode. A multi-wire version is shown. A future advanced electronic filter is shown which automatically replaces confidential data like a social security number with a set of dummy data while browsing on the Internet.
