Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

Global revenue in the aircraft relay and contactor market has declined by more than 20 percent as a result of the ongoing Covid-19 pandemic. The market decline is expected to stabilize in 2021, ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

Relay testing goes beyond theory—real-world challenges demand adaptability, precision, and experience. Join us to explore ...

Reed relays have evolved from their audio roots to handle GHz signals; MEMS technology may push them aside. This section ...
