标题: The Function and Applications of Electromechanical Relay

    An Electromechanical Relay (EMR) is a fundamental component in electrical engineering, playing a vital role in automating and controlling electrical circuits. It is a device that uses an electromagnetic coil to open or close a set of contacts, which in turn can control a larger current or perform other electrical functions. Despite the emergence of more advanced technologies, the electromechanical relay remains a widely used and trusted component in various applications due to its simplicity, reliability, and versatility. This article aims to explain the working principle, types, applications, and advantages of electromechanical relays.
