I would guess that you are looking at the Bosch style cube relays. They are
capable of larger currents, but not much voltage without the insulation
breaking down. If you have access to one open it and take a look yourself.
Also I would assume that there is too much coupling to the coil via stray c at
higher power levels.

OK... Just asking. No one laugh.... Automotive relays are fairly cheap and
you can get them just about anywhere. 12 volts switching voltage....and they
care a lot of DC amps. So, could one use those for switching RF or is that a
laughable idea?

In our day and age it seems that Common Sense is in short supply. If you don't
have any Common Sense - get some Common Sense and use it. If you can't find any
Common Sense, ask for help from somebody who has some Common Sense. Is Common
Sense divine?
Common Sense is the image of the Creator expressing revealed truth in my mind.
