Relays are switches that are operated by an electromagnet to open or close (turn off and on), given the right amount of electricity is flowing through the switch. These allow the electrical system to operate with a bit more safety, for if not enough energy is running through the system, the Relay will not Open or Close, making the system either turn off, or on. One of the most simple yet complex electrical components, they have many uses, and here at All Battery Sales and Service you can get what you need at low and competitive prices.
