- 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
- What Is Relay? How Relay Works? - Electronics Hub
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
- What Is Relay And How Does It Work? - Regent Electronics
A relay is an electromechanical switching device that allows a low-power signal to control a high-power circuit It is widely used in automation, electrical protection, and remote control applications Historically, the concept of relays dates back to the early 19th century
- How Relays Work - HowStuffWorks
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
- 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)
