Automotive relays are electronic switches used in vehicles to control power. They help modernize electrical conveniences and safety features in all kinds of vehicles. They work by automating power switching between various circuits, which can include various voltage types. An automotive relay's design is based on electromagnetism, which means that it activates contacts when an electrical input is given.

There are two types of automotive relays: change over relay and make and break relay. Each one has a high current circuit and a contact that is either normally open (NO) or normally closed (NC). The position of the contact depends on the type of relay and its design. Normally open relays have a broken contact at rest, whereas normally closed ones have a closed contact. The switch used to activate a make and break automotive relay is typically a toggle switch or push switch. You may be familiar with these switches from your daily life - the ignition switch on your car, for example.
