Custom button having issues

[ScaryMonkeyMan]

So making my first mod using a Hammond 1590b enclosure and a wired fire switch. I noticed it wouldn't fire if the threads of the switch were touching the inside hole. Is there something I should be using to insulate the two from touching or is there another issue that needs to be addressed?

Well took the button out and tried rewiring and now it seems to work so my only guess is maybe there was dust or something causing to ground or possibly a polarity issue. Time will tell if it holds up or if the issue comes back
