What is an automotive relay? In simple terms, an automotive relay is a small cube shaped electronically operated electromechanical switch. It uses an electromagnetic device to mechanically maneuver a ...

The relay's primary appeal is its ability to do a lesser-switch's bidding but it's capable of so much more. Relays can be wired together to create very useful, simple, and utterly reliable networks.

An automotive relay works by using electromagnetism to change small levels of input electricity into larger current outputs. When an electric signal is sent to the relay, electromagnets form or break ...

As the content of electronics along with electronic control modules continues to climb in vehicles, the need for smaller relays that carry greater current loads continues to grow, particularly for ...
