estop switches was Re: Advice needed - Mariss' e-stop circuit

Dave,list,

Most safety standards REQUIRE that the estop NOT be momentary...

That is why most switches sold as estop require turning the face of
the knowb to reset. Older switches could be pulled out, but newer
safety regulations have made these obsolete on comemrcial equipment.

Hope this helps,

Ballendo
