An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

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 ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...
