A relay is an electromagnetic swap that makes use of a small electrical sign to manage a bigger electrical sign. Relays are utilized in all kinds of functions, together with industrial management, telecommunications, and automotive methods.
There are various several types of relays, however the commonest kind is the electromechanical relay. Electromechanical relays have a coil of wire that’s wrapped round a metallic core. When {an electrical} sign is utilized to the coil, the core turns into magnetized and attracts a metallic armature. The armature is linked to a set of contacts, that are used to manage the stream of electrical energy within the bigger electrical circuit.
