Hi, sorry if this has been gone over before ... for smaller tube mods, like a 14500, where conventional switches are too big, what would be a good way to mount a tact switch up against the curved inner surface? Thanks in advance.
How do you mount a tact switch inside a tube mod?

I mount mine to a PCB .WIth the curve the pcb sits flat at two ends where i mount it with epoxy. I try to also shim it with something so no matter what it cant be pushed in.
I use switches mounted on board. If you want to use a switch separately and precisely mounted, use a hot glue gun. Carefully, a few layers, wait until every layer gets cool enough.
If you have not a glue gun, buy a 5-minutes epoxy or acriylic compound. You will need some training to work with them. Use a very small pieces of a tissue to hold the resin in place.

I drill and tap the hole and thread the pushbutton switch in. Tact switches are rated too low to handle the load unless you use a mosfet
I also grind down the length of the plunger

You're using the C&K switch, right? Since I like copper and you're the copper mod king I've copied you a lot but I can't thread that switch inside a piece of 1/2" I.D. copper. I bent the pins and installed it through a tight hole to see if it would work and it was pretty tough but doable, so I took it back out soldered the wires and just used the nut. I don't doubt at all that you did it, would it be to much to ask...how you did it? 
The movable part that you depress which slides into the threaded barrel.
IMO it looks a lot better with a short stub protruding rather than a long one.

Robert, the CK PB body would fit in a 1/2" tube but with the length of the threaded barrel it would be impossible to angle it in to thread. Yes you would have to use a slightly bigger hole and use the nut. - 8552MZQE2 has a shorter body length (0.315) than the 8551MZQE2 (0.427). I was using it in a 3/4" tube.
ahh ,I was picturing trying to grind down a actuator on like a horn switch or NKK switch . On tact switches i also grind down the plunger.
I used part of a tube of a syringe that fit just inside my tube. Put all of my electronics into the syringe, used hot glue to secure it, then just slide it in and maybe a little glue on the inside of your tube to hold it in place. Very easy to do!
Thanks for the part number: 8552MZQE2 ... I had not found a switch that small so thats why I thought I would have to go tact switch and some electronics ... looks like it would be real tight but workable ... ... umm ... what is this C&K switch you guys are talking about? (excuse my ignorance)
Edit: Sorry, I get it, those swiches are made by C&K components.

Thanks Breaktru, if I build another device using 1/2" copper I will definitely be using that switch.
