The present invention is directed to a protective wiring device that includes a rear cover member having a portion substantially defining a line terminal interface region. An electric circuit assembly includes a sensor assembly coupled to a fault detection circuit. A plurality of line terminal interface contacts are disposed in the line terminal interface region, each line terminal interface contact being connected to a termination structure coupled to the rear body member. A conductive pathway is configured to interconnect the termination structure and a corresponding one of the first set of contacts via the sensor assembly. The conductive pathway includes a conductive structure disposed in the rear cover member and mounted to the at least one PCB. The line terminal interface contacts are configured to mate with a removably attachable electrical adapter connected to the plurality of AC power transmitting wires to provide AC power to the electric circuit assembly.

A load control switch (1) is provided with a terminal module (2) to which electric wires are connected and which is installed on an installation frame established on a wall surface of a building; and a switch module (3) which is detachably mounted to the terminal module (2) and which turns a load on or off. The load control switch (1) is also provided with an operation handle (4) detachably attached to the switch module (3). The switch module (3) may be an electronic switch or a mechanical switch; an electronic switch may additionally be provided with delay function, timer function, a motion sensor, and so on. This makes it possible for a user to freely replace one load control switch with another having different function without electrical work being required.

A communication connector with analog coupling circuit and a mechanical coupling circuit used for providing security to electronic devices. The analog circuit includes a male plug with an outer shell and tongue shell. Between the outer shell and tongue is a thin layer of non-conductive material to prevent the closure of a circuit. Two separate conductors are wired through the USB body; one attaching to the outer shell and the other attaching to the tongue. A closed circuit is created when the male USB is placed into a female receptor. The mechanical circuit creates a closed circuit when the plunger switch becomes compressed. There is a security monitor system connected to an end of the two conductors, which sound an alarm when circuit is opened. The alarm will sound if a thief attempts to steal the article either by cutting the wire or removal of the plug.

In a grinder, a terminal plate is projectingly provided on an upper surface of a controller. A connection portion, which accommodates a female terminal and includes a slit into which the terminal plate enters, is projectingly provided on a lower surface of a main body portion of a switch block. At the time of assembling of the switch block and the controller, the terminal plate that enters into the connection portion from the slit is inserted into and connected to the female terminal. First and second projections that cover a formation surface of the slit in the connection portion when the connection portion is inserted with and connected to the terminal plate are formed on the upper surface of the controller.

An electrical switch and outlet design which includes a modular electrical component system having a universal connector which can receive replacement switches, sockets and other electrical components. The connection between these switches, sockets or other components and the universal connector is controlled by a lifting system in which the entirety of the replacement module is inserted into a receptacle or removed therefrom without the user touching any electrical wiring. Essentially, components are changed by plugging a component into and unplugging one from a universal grounded connector.

The present invention is directed to an electrical wiring system for use in an AC electrical power distribution circuit including at least one first AC power conductor disposed between an upstream AC power element and a device box and at least one second AC power conductor disposed between the device box and a downstream AC power element. The at least one first AC power conductor and the at least one second AC power conductor are routed into an interior portion of the device box and accessible via a front open face of the device box. The system includes a connector device including a connector housing having a plurality of connector contacts disposed therein.The plurality of connector contacts are coupled to termination structures configured to couple the at least one first AC power conductor and the at least one second AC power conductor to corresponding contacts of the plurality of connector contacts. An electrical wiring device includes a device housing having a front portion and a rear portion. The front portion includes at least one user-accessible control element disposed thereon. The at least one user-accessible control element is coupled to an electrical switch mechanism disposed in the device housing and coupled to a plurality of device contacts. The plurality of device contacts are accessible by way of a device connection arrangement formed in the rear portion of the device housing. The plurality of device contacts are configured to mate with the plurality of connector contacts when the connector device is coupled to the device connection arrangement.

A diode unit (9) including at least one diode (13) and a pair of terminals (15) is mounted on a switch body (2) having an actuate-able key (6) and at least two terminal points (4). The diode unit (9) is positioned on the exposed end of the key (6) such that surface parts of the diode unit (9) is brought into engagement with corresponding surface parts of the switch body (2) so as to prevent the diode unit (9) from movement in relation to the switch body (2) in a predefined plane. The diode unit terminals (15) extend in a direction transverse to said plane, and the diode unit terminals (15) are connected to the terminal points (4) of the switch body (2) so as to prevent movement of the diode unit (9) in relation to the switch body (2) transversely to said predefined plane.

A line terminal for a circuit breaker includes a body forming two opposing legs and a third leg. The opposing legs are configured to form a passage for receiving a stab from a panel board. The two opposing legs are biased toward each other, and each of the opposing legs has a convex surface facing the passageway for engaging and maintaining alignment of the stab. A fixed contact is attached to the third leg. The fixed contact connects to a moveable contact of a circuit breaker. An arc runner is connected to the third leg and at least partially encloses a perimeter of the fixed contact.

A modularized switch connector having a shovel shaped insulating housing formed integrally, the housing is shaped in matching with the shape and contour surrounding a first and a second electrically connecting pin as well as a grounding electrically connecting pin of a micro switch. The housing is formed thereon a first and a second through hole, and is formed on its lower forwardly protruding portion a third through hole. The rear end of each hole allows inserting of an electrically conducting jack with a “U” shaped section therein. The front end of each through hole allows inserting of an electrically connecting pin of the micro switch; so that the first and the second electrically connecting pins of the micro switch can be connected with two electrically conducting jacks in the first and the second through holes, while the grounding electrically connecting pin can be connected with the electrically conducting jack in the third through hole.
