A power relay is an electrically operated switch that is used to control the flow of electrical current in a circuit. It consists of a coil of wire, a movable armature, and a set of contacts. When an electric current is applied to the coil, it creates a magnetic field that activates the armature, causing it to move and close the contacts. This allows the relay to control the flow of electricity to a load, such as an electric motor or a light bulb, by switching it on or off.

There are several benefits to using a power relay in electrical systems:

  1. Isolation: A power relay allows electrical current to be switched on or off without the need for a person to physically touch the wires, providing a level of isolation between the user and the electrical circuit.

  2. Safety: Power relays can be used to automatically disconnect power to a circuit in the event of an overload or fault, helping to prevent electrical fires and other accidents.

  3. Control: Power relays can be used to control the flow of electrical current in a circuit, allowing for precise control over the operation of electrical devices.

  4. Efficient: Power relays can be used to control high-power loads with a low-power signal, making them more efficient than other types of switches.

  5. Reliability: Power relays are known for their reliability and long life, making them a popular choice in electrical systems where dependability is important.



Kevin, my error. I actually located the item. I do appreciate your help. I have to tell you, my experience with CompSource from beginning to end has been great. The first time I went to your site was for this order. I wasn't sure what it was I really needed so I called and your man was super helpful walking me through the order process and making sure of my application and recommending the right products. jpowers1127
