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.

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Electromagnetic contactors and relays serve as fundamental components in modern electrical systems, providing reliable switching mechanisms in applications ranging from power distribution to ...

Love it or hate it, wiring is a part of any project car. You may loathe the idea of installing relays, but without them, wiring would be much more difficult. HOT ROD ...

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 ...

Manufacturers of switches and relays have faced several big challenges over the past few years. OEMs, particularly in higher-reliability markets, continue to look for greater flexibility and ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
