I am using and emergency stop in an application. It is a push button with a twist release. I have the main circuit connected to the normally closed side and a detection circuit wired to the normally open side.
When the stop is activated, the normally closed switch of course opens and remains open (until I twist release the stop).
However, the normally open switch closes only momentarily. Do emergency stops exist in which the normally open switch will remain closed until twist released. If so, what keyword should I look for in searching for such an emergency stop?
