Special Tool for this?

I use this guy:

Threaded one way to loosen, one way to tighten, fits any size dress nut it'll fit over. I usually put some tape down on the faceplate to protect things while I do the work. Been great, had one for a long time now.

 

So wait, yours doesn't seem to have the little reeded edge washer like this guy?



You only have the piece shown?

 

I guess it's gonna be multi-reply day for me

For the ones like you pictured, now that I'm paying attention, I just get them finger tight and then finish it off with a flat head screwdriver with some light pushing or gentle taps with a small hammer.

 

The british call any wrench a spanner, but we yanks use the term differently.
There are ones that are rigid for particular applications and adjustable ones.
If you have an angle grinder, a spanner is what's used to change the disk.

 

Those needle nose pliers are not the proper tool but will work. put the tips in the slots with the pliers perpendicular to the switch nut.

 

I think any of the spanners/ring pullers would have rounded tool tips that are too large, but you may be able to file them down to get them to work.

 

Gotta admit...in a pinch, I'd probably use the needle nozers.
Or this tool from my bike tool stash

 

I have one that the one on the left...



I filed and smoothed the parts of the jaw that contacts the surface so that it won't scratch.

the right snap ring pliers will work too.

 

This what you are looking for?

Also called a "panel nut wrench" or socket.

 

I use one of these, if I need to. Although, I usually replace the dress nut with a regular hex nut on Carling switches in Fender builds.

put the point tips in the holes and turn..I have done this many times and it works..youre welcome!

 

The ones that @galaxiex posted are the right deal - I hadn't come across an official tool for that before.

 

I grip the nut with my fingers and turn the switch body with my other hand to give it the final snug up. I can't get it extremely tight but I have never had one come loose on it's own.

 

I have several size sockets for those. Seems the @#&*%#$!@ automotive engineers were crazy about them in the 50's to the 80's. Fortunately, only antennas use them nowadays.
I can't tell you how many times I have used 3 flat blade screwdrivers, (1 in each notch, and 1 between those two for leverage). Right angle snap ring pliers will also work!

 

I have a set of those as well. It's the correct tool.

 

Yeah, I use an angled tip long nose plier.
