Unless I suddenly forgot how to use a meter, the grounds are isolated.
There
is also a visible plastic (teflon?) ring at the base of each coax.

That's 6 BNC connectors, the switch has only three.

The first time I heard of all-pass filters, I said to myself: what's
the point?
I could say the same about Earthlink's filter (all-reject): what's the
point?

Really!? I don't think I have ever seen a coax switch or relay where all
the grounds (shields) weren't always connected together.

The local surplus guy got in a few dozen coax switches. The only markings on
them say Type DSWA0. Dimensions are about 2.6 H x 2 D x 1 W. There is a
toggle switch on the front and three BNC connectors on the back.
I can't find any information about these. Does anyone know anything about
these?

Just a guess, but SPDT toggle switch ?
How much does he want for them ?
Regards, Dick, W1KSZ
I would assume so. I have one and will have to put a meter on it. I was
curious if anyone knew what frequency range these might be good
I assume these are *signal* switches, as opposed to *power* switches?
Didier
Well, as I said, they have BNC connectors on them. Also, from the markings
on the panel they were mounted in, they were part of some type of telemetry
system.
I was going to try hooking the one I have up to a signal
