Here’s an interesting introduction to Reed Relays, Mercury Displacement Relays, Contactors, Polar Relays, Latching Relays, T-Bar Relays, Time Delay Relays, and Stepping Relays. Here’s an interesting ...

Evolving from magnetic coil actuators to capacitive-coupled isolation, the ever-shrinking relay continues to be an essential component within the automation arena. Modern relay technology has been ...

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 automation expands, mechanical functions are relying more and more on electronic control. Solenoids provide an electromechanical interface for many of these applications. In addition, 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 ...
