nocaster black plastic selector switch keeps falling off

Short of dropping some glue inside the switch tip, try what I did: wrap a small piece of paper around the selector, then push the tip on. Should do it.

 

Wrap a small piece of black tape around the metal switch and push on plastic tip. I'll be sticky and then dry to keep it in place!

 

try a little piece of hockey tape. it gets sticky and stays that way. My Tele does the same thing...annoying.

 

I had the same issue with my Nocaster Relic.

I used clear nail polish and have not had a problem since. If I do ever need to remove the barrel tip, it won't be too hard to do.

 

On my strat I just pinched the metal switch tab with some pliers till there was a little burr for the switch to grab onto.

 

That's a good solution.
Fortunately I don't have this problem on mine.

 

Same Problem. Tape or nail polish both worked well for me.

 

I finally solved that problem....
My tip never falls out of the case!!!

 

I lucked out on my old tele, it was impossible to take off!

 

Works with wire cutters too.

 

This or tape have done the trick, for mine.
