Jerry,

You are absolutely right, it's a Baumer! I looked at the Baumer
website, and found the exact switch, the only question is what
activation pressure the switch is.

Now, I feel much better knowing that I don't have to pay double to
get it from the machine manufacturer. However, there are three
switches on each machine, and I have three machines. So, what do you
think about ultrasonic cleaning of the Baumer switch? I thought I
could clean the switches in a water soluable cleaner(in the
ultrasonic bath), then rinse them in straight water(in the ultrasonic
bath), then gently warm them on a heating pad of some sort to dry
them out. Then perhaps attempt to get a drop of very light oil past
the plunger.

I know it sounds like a lot of diddling around, but I've got a lot of
switches to do, so I stand to save a couple of bucks if it works.

At any rate, thanks a bundle for steering me in the right direction
to identify the part.

Thanks,

Patrick
