The SS-3FP/SS-5F Subminiature Basic Switch from Omron features a 1-mm contact gap. The switches comply with the IEC standard for insulation distance required in secondary circuits of interlocks. This switch can be used in a variety of applications such as door interlocks and secondary interlock systems for office equipment and security devices, among many others.
Leland Teschler, Executive Editor email@example.com On Twitter @DW_LeeTeschler Those who’ve watched the engineering profession over the years might become suspicious when a prominent scientific organization studies employment in the field. The reason for this wariness arises from previous proclamations from the National Science Foundation which has had a reputation for forecasting fake engineering shortages. One
Lee Teschler – Executive Editor firstname.lastname@example.org On Twitter @DW—LeeTeschler In olden times when there were no such things as cell phones, Uncle Sam regulated the phone system. Phone companies charged their customers for every handset attached to the lines and used time-domain reflectometery to check phone lines for illegal handsets. Thus began a ritual of
The recent North American International Auto Show — the Detroit Auto Show for short — is known for highlighting the debuts of new production vehicles and concept cars. But a lot of automotive suppliers also use NAIAS to highlight new developments in component and subsystem technology. We have put a few of the more interesting
The North American International Auto Show (NAIAS) is known for hosting debuts of new-model vehicles. But some of the more interesting technical developments at the show don’t appear on the vehicles that get the lion’s share of the press coverage. What follows are some of the vehicles we noticed that seemed to host noteworthy powertrain

Leland Teschler, Executive Editor firstname.lastname@example.org On Twitter @DW_LeeTeschler Most engineers have probably been in a few job interviews that didn’t pan out for reasons that, afterward, seemed a bit ambiguous. In at least one corner of the tech employment industry, there is a move to eliminate some of the goofier outcomes that can arise in
Lee Teschler Executive Editor @DW_LeeTeschler That’s not how we do things around here. As with many young engineers, I used to hear that phrase a lot when I was first starting out. Though often meant as well-intentioned advice, it was like fingernails on a chalk board for somebody who had what today is called an

Leland Teschler Executive Editor email@example.com On Twitter @DW_LeeTeschler Recent events have gotten a lot of people concerned about personal attacks, name calling, and reputational smears. No, we’re not talking about the presidential election. Sadly, it is becoming almost as easy to find examples of bullying and defamation in scientific and engineering research as in politics.
