- 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
- 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

- What is Relay? - GeeksforGeeks
A relay is an electrically operated switch in the context of electronics and electrical engineering It is made up of a coil and one or more contact sets When an electrical current runs through the coil, a magnetic field is created that activates the contacts, allowing them to open or close the circuits Relays are frequently employed in automotive applications, industrial automation, and
- What is a relay, its function, types and relay wiring
Normally open relays are switches that are opened by default This means that the electrical current will flow through the switch when it is in the open position Normally closed relays, on the other hand, are switches that are closed by default
- 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
