Many devices called relays use similar techniques and topologies, but the terminology can be confusing. Here are a few of the basic differences that distinguish different types of relay and contactor switches.</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/engineering-essentials/engineering-essentials-relays-and-contactors" target="_blank">read more</a></p> http://machinedesign.com/engineering-essentials/engineering-essentials-relays-and-contactors#comments Engineering Essentials Thu, 31 Jul 2014 17:57:00 +0000 39861 at http://machinedesign.com Electroformed Parts http://machinedesign.com/materials/electroformed-parts <div class="field-deck"> Sponsored by Servometer </div> <div class="node-body article-body">What is an electroformed part?
