What Is Relay? How Relay Works? - Electronics Hub Relay works on the principle of electromagnetic induction When the electromagnet is applied with some current, it induces a magnetic field around it Above image shows working of the relay
How Electrical Relays Work - Circuit Basics 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
Relay - Wikipedia A relay is an electrically operated switch It consists of a set of input terminals for a single or multiple 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
How Relays Work - HowStuffWorks Relays contribute to safety by allowing low power control circuits to switch high power loads, reducing the risk of electrical hazards in control interfaces Powered by electromagnets, a relay is simply a mechanical switch, and you’ll find them all over a typical house or car
