Relays

Relays are an important component in many electrical systems, serving as a switch that allows electrical signals to be transmitted from one circuit to another. Essentially, a relay is an electrical switch that is operated by an electromagnet rather than a person. They can be used for a variety of purposes, from controlling large motors to switching high-voltage circuits. Relays are a critical part of many industrial and commercial applications, and they play a key role in automation and control systems. As such, understanding the basics of relays is essential for anyone working in the field of electrical engineering or automation.
