Testing old corroded industrial switches can be tough with low level ohmmeter.
Even my Simpson260 was giving me false negatives.
So I dig out an old electricians test light that I found in a barn.
They were pretty standard back in the day. My uncle (electrician) had on on the bench when I was about 10 years old.
Remember asking him why he didn't get shocked lighting a 120vac bulb.
Didn't take a little kid seriously, and for an answer he touched the probes.
I've always wondered what was in that magic box.
Assumed it was some type of transformer connection as there was no click from a relay.
Today I peeked.
This isn't the same one. Hope he new better.
ps.
As per another thread. Look at the knurled nut.
