What is the NO SPST normally open relay? The NO Normally-Open SPST (Single Pole Single Throw) relay has an opened circuit state when no current is applied to its coil so basically it disconnects the ...

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 ...

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.

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 ...

IRVINE, Calif.--(BUSINESS WIRE)--Menlo Microsystems, Inc. (Menlo Micro), the company responsible for bringing to market the greatest electronic component innovation since the transistor with its Ideal ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

This MOSFET-output optocoupler provides an SPST relay function and targets the high voltages of electric-vehicle battery packs. In many designs, a suitable single-function building-block component ...
