Non-Latching Relays

Relays are switches that are operated by electrical impulses. The two major types of relays, latchingand non-latching relays, have this in common, but they have other differences that make each more suitable for different applications. Non-latching relays are particularly suited for push-button applications.

How do non-latching relays work?

A latching relay stays where it was when the circuit was last powered. A non-latching relay, by contrast, goes back to its normal position when the power is removed from the circuit. This difference may seem small but it's very significant in terms of the applications that a non-latching relay is suitable for. It makes non-latching relays well suited to push-button applications like keyboardsand micro-controller input buttons. They come as plug-in or PCB-mount designs.

What are non-latching relays used for?

Non-latching relays have a wide range of applications. They are used in aerospace technology, agricultural equipment, air conditioner, engines, forklifts, household appliances, industrial machinery, medical equipment and telecommunications equipment.
