- Relay - Wikipedia
A relay is an electrically operated switch It has a set of input terminals for one or more control signals, and a set of operating contact terminals The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof

Instead of mechanical operation, a relay deploys an electrical signal to drive an electromagnet, which in turn engages or breaks (connects or disconnects) another circuit Relays can be of different types like electromechanical, solid state Electromechanical relays are frequently used

Explore the fundamentals of relays, their types, components, and real-world applications in electrical engineering
- How do relays work? - Explain that Stuff!
A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it)

Commonly found in both household appliances and vehicles, relays enable electronic controls to operate high-power circuits like motors and lights efficiently You can also use them in cascades or for Boolean logic operations to manage complex switching arrangements
- Electrical Relays: How They Work and Their Applications
What is an Electrical Relay? An electrical relay is an electrically operated switch that uses an electromagnet to control one or more sets of contacts Relays allow a low-power signal to control a high-power circuit, providing isolation and control flexibility
