What does Relay mean in Technology Dictionary?

  • A relay is an electrically run or electromechanical switch composed of an electromagnet, an armature, a spring and a set of electrical connections. The electromagnetic switch is operated by a small household current that turns a bigger up-to-date in or off by either releasing or retracting the armature contact, therefore cutting or doing the circuit. Relays are necessary whenever there must be electric separation between controlled and control circuits, or when several circuits have to be managed by just one sign. by SaulReport definition
