WebHow does it work? When current is applied to the coil it will pull the contact (which is normally open) closed allowing current to pass through the contact side of the relay. Some relays have multiple options on the contact side of the relay. They can have both a normally open (NO), or normally closed (NC) set of contacts. WebRelays are magnetic electromechanical devices with two primary purposes: to isolate different circuit voltages, and to form larger complex networks of logic to run machines without digital controllers. An electromechanical relay is an electrical switch actuated by an electromagnet coil.

WebA relay is an electrically operated switch. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated. The example relay diagrams below show how a relay works.
