Electrical circuit-interrupters AFCIs (arc-fault circuit-interrupters) protect against fire by continuously monitoring the electrical current in a circuit and shutting off the circuit when unintended arcing occurs. These devices are designed to discriminate between unintended arcing and the type of arcing that occurs when a switch is operated.

Network switch Network switch. A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.

GFCI Basics A GFCI is only as good as its installation and inspection. A ground-fault circuit interrupter (GFCI) is the only protection device designed to protect people against electric shock from an electrical system. Because of this, we need to understand what a GFCI is, how it works, and what its limitations are. We need only to look to the NEC for the definition of a GFCI.

How To Choose Circuit Breakers A circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short. Homes built or rewired since the mid-1960s use circuit breakers to monitor the electricity coming into the home.

Switch Types and Common Terminology A switch is a device that is used to make and break the connection in an electric circuit. A switch can also be called a relay. Although these two terms are often used interchangeably, typically when talking about an individual switch it is referred to as a relay and a switch is a combination of relays.

Switch Basics A switch is a component which controls the open-ness or closed-ness of an electric circuit. They allow control over current flow in a circuit (without having to actually get in there and manually cut or splice the wires).Switches are critical components in any circuit which requires user interaction or control. circuit diagram with an LED, resistor, and a switch. When the switch is closed, current flows and the LED can illuminate. Otherwise no current flows, and the LED receives no power. There are tons and tons of switches out there: toggle, rotary, DIP, push-button, rocker, membrane, … the list just goes on and on.

- How a Transfer Switch Works. In electrical talk for using alternate power sources, a transfer switch is a break before make switch. That simply means that it breaks the main power circuit from the utility before it makes a circuit from the other side for your personal generator.

Switch Definition - What does Switch mean? A switch, in the context of networking is a high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN). A LAN switch operates at the data link layer (Layer 2) or the network layer of the OSI Model and, as such it can support all types of packet protocols.

Relay A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings. A contactor is controlled by a circuit which has a much lower power level than the switched circuit. Contactors come in many forms with varying capacities and features.

Immobiliser An immobiliser or immobilizer is an electronic security device fitted to an automobile that prevents the engine from running unless the correct key (or other token) is present.This prevents the car from being  hot wired  after entry has been achieved and helping to reducing motor vehicle theft.ater models use rolling codes or advanced cryptography to defeat copying of the code from the key or ECU. The microcircuit inside the key is activated by a small electromagnetic field which induces current to flow inside the key body, which in turn broadcasts a unique binary code which is read by the automobile's ECU.

Protective relay An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. The ANSI device number is 50 for an instantaneous over current (IOC) or a Definite Time Overcurrent (DTOC). In a typical application the over current relay is connected to a current transformer and calibrated to operate at or above a specific current level.

Lightning arrester A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth.

Is-limiter applications to reduce high short-circuit currents The trend towards higher line kVA ratings and the growing intermeshing of power systems are increasing the likelihood that distribution switchboards will be subjected to unacceptably high short-circuit currents. Reliable and economic protection against these surge currents is provided by the Is-limiter. This fast-acting switching device triggers a small charge to open the main conductor, which is designed to carry high operating currents. The current commutates to a parallel fuse with high breaking capacity, which limits the short-circuit current during the first rise. Is-limiters are being used successfully in more than 2.500 stations in 70 countries.

Interrupts Interrupts. An interrupt is an indication to a thread that it should stop what it is doing and do something else. It's up to the programmer to decide exactly how a thread responds to an interrupt, but it is very common for the thread to terminate. This is the usage emphasized in this lesson.

AN INTRODUCTION TO INTERRUPTS The processor can inhibit certain types of interrupts by use of a special interrupt mask bit. This mask bit is part of the flags/condition code register, or a special interrupt register. In the 8086 microprocessor if this bit is clear, and an interrupt request occurs on the Interrupt Request input, it is ignored.
