WebHow Does an Electrical Relay Work? An electrical relay works by using a small signal to activate an electromagnet, which then switches a larger electrical load. This signal can come from a variety of sources, including sensors, timers, and switches. The relay itself is made up of several components, including the electromagnet, the armature ... 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.

A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current.
