I need to put a momentary on switch in my dashboard, and the one I
bought doesn't have a hex nut for the top nut but a round serrated ring
to hold the switch in place.

How do you tighten this? I don't see how fingers can do as good a job
as a wrench did with the hex nut, and pliers will scratch it up.

I could find an old hex nut, but I'd rather use the pretty round one,
if I can.

Use some cloth to cover the nut and then use pliers. Just don't grip too
tightly or it can tear through the cloth.

Okay, I'll do that. Maybe I can just hold the nut that way and turn the
hex nut behind the dash next to the box below the radio and above the
consoleradio. In this case, I'll have access to it.

It's interesting to learn, Tom, that there is a special tool

Thanks all.
