WebA relay is an electrical switch that converts tiny electrical impulses into bigger currents using electromagnetism. 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.
