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.


The cloth is more to protect the surface of the panel the switch is mounted
to than to protect the knurled round nut you are trying to tighten.

I'm not sure what that means. It will protect whatever you put it over. I
use a cloth when tightening plumbing hardware that often is chrome plated.
That can require some heavy tools and a cloth works great as long as it is
not too thin and tears.


If you
can tighten the hex nut underneath that is better of course! A split or star
lock washer is good between the hex nut and panel...

Yes, if you can get to the back nut, that would not only prevent scratches,
but let you set the switch protrusion from the panel to exactly the right
amount.
