A relay is an electrically operated switch. It has a set of input terminals for one or more control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.
A relay is an electromechanical switching device that allows a low-power signal to control a high-power circuit. It is widely used in automation, electrical protection, and remote control applications. Historically, the concept of relays dates back to the early 19th century.
Electrical relays are crucial because they enable the control of high-current loads using a small amount of electrical current. Relays apply voltage to the coil, which causes a low current to flow through it. This allows a larger current to pass through the contacts and control the electrical load.

A Relay is a simple electromechanical switch. While we use normal switches to close or open a circuit manually, a Relay is also a switch that connects or disconnects two circuits.
Electrical relays are switches that you turn on and off with electrical signals. In this guide, you’ll learn how a relay works and how to use relays in your own electronics projects!
A relay is an electromagnetic switch that opens and closes circuits electromechanically or electronically. A relatively small electric current that can turn on or off a much larger electric current operates a relay.
