What is the normally closed SPST relay? The NC Normally-Closed SPST (Single Polse Single Throw) relay has an initial closed circuit state when no current is applied to its internal coil therefore it ...

A1B-E, a 300-ampere, 1000-volt relay that provides a printed circuit board (PCB)-mountable option for high-current applications traditionally served by electromagnetic contactors. Creds: OMRON The new ...

The relay's primary appeal is its ability to do a lesser-switch's bidding but it's capable of so much more. Relays can be wired together to create very useful, simple, and utterly reliable networks.

What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

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 ...

The MightyMUX high-performance analog switch line recently ushered in the ISL84521, ISL84522, and ISL84523 switches and their 10-nA maximum leakage currents. Such leakage currents help lengthen hold ...

There are standard designations and symbols that describe how electrical contacts work in specific scenarios. These designations spell out the number of contacts and how they behave during operation.

Electronic devices are built from many different parts. Understanding how these components work together is key to understanding electronics. Circuit diagrams use symbols to represent each component, ...
