Excellent work FranK ... more "stealthy" can't be done!!!
Yes, I put 3 holes inside the button for extra side pins Ariel. You know that all these years I put extra things on all my constructions in case someone has an issue, so he can solve it easily.I do not know if Imeo made the inner part of the GG4S button with two extra holes for "Buttons Side Pins" for this purpose:
The center part of the button of one of my GG4Ss was getting little hot when using resistances below 0.7 ohms (which I do not usually use), of course, I cleaned meticulously the GG4S, all its individual parts and the battery poles, but from time to time I could feel the button was getting little hot.
I installed an extra "Button Side Pin" (for a total of two) and problem solved, no more hot button
A friend was having exactly the same symptom with his GG4S, he told me that were the batteries, the issue vanished when switching the battery for a newer one (maybe some batteries were not healthy enough to support the required current).
Anyway, for sure an extra "Side Button Pin" doesn't hurt and it could improve the conductivity
For a quick fix and what I ended up doing with my GG4S after much cleaning with reading glasses on and off lol I took Imeo's advice I tighten the center pin like normal than back it off a half turn fires everytime and the hot button goes away. I think I over tightened it to many times and compressed the o-ring to much.
