How Does a Relay Work? Explained With its Construction
WebSep 10, 2024 · A coil of wire wrapped around a laminated iron core provides the magnetic field necessary to actuate the switch mechanism. This particular relay is equipped with normally open (NO) switch contacts, which means the switch will be in the open (off) state when the relay coil is de-energized. WebApr 14, 2024 · Relays can be used as switches to turn things on and off, or as amplifiers to convert smaller currents into larger ones. They can also be used to control a circuit with a low power signal or when multiple circuits need to be controlled by a single signal. There are two kinds of relays, electromechanical and solid state. WebControl relays are an extremely important electrical part, and they play a vital role in today's electronic devices.
