Yeah try the brass screw really cheap and with all the sizes available might do the trick further you could replace both top screw and the pin in the bottom as well.
My Authentic Atomo has the same issue. I went with a heavier better conductive spring and it fixed the issue. The spring helps create a better pathway for conductivity from the button to body. Many mods, authentic or clone, have this issue. Magnets reduce the pathway unless they touch at the precise time the negative post touches the battery.
So that's funny because my gnome clone--which has the atomo clone's recessed magnetic switch--is the best switch I've ever used! The gnome has supplanted my stingray in the last month as my go-to mod.
I noticed the spring is in contact with the bottom button and the other end rest on the plastic washer that is used to adjust battery wiggle. Other versions Ive seen have this plastic part mount on a piece of brass. so the spring touch the bottom button then the top brass and that touched the mod wall. In that sense is the spring also making the connections? If so could i put a tight fitting copper washer in there that would link the spring to the side wall of the body?
i used a piece of copper tape, rapped it around the inside where the fire button rides. seems to have fixed it so far. i only just it did as i was reading. it took the hot button problem away to.
I had this problem on my dreadnaught, checked continuity of the mod, checked charge of the batteries, everything was all good, I took the switch completely apart and put it back together, then all I did was thread out the delrin in the throw contact, even tho the 26650 is too long for the chamber as is, but it's been firing ever since. Some how by playing the delrin a bit, or loosening it off some, it allowed the contact to do just that, contact. I wish I knew why tho
Yeah man the battery is totally too long for the mod, I got the efest 26650 greens, and yeah the bottom threads on not all the way and the brass decorative sleeve does rattle, there's nothing I can do about it, kinda garbage But you do just get used to it. As for the issue with the sketchy firing, I figured out what was going on, the contact in the bottom piece definitely has no problem making good contact with the bottom of the battery, however it seems to have trouble maintaining good contact with the walls of the housing of the bottom piece, which is how the circuit completes it's continuity. So what I did was, I unscrewed the delrin in the bottom piece, the black plastic that pushes up against the bottom of the battery, it acts as a guide for the contact as well as houses the spring in the switch mechanism, take that off, I then took a piece of regular aluminum foil, and folded it in a little strip, I then took that strip and shaped it into a small ring which I then fitted down into the space where the spring goes, around the outside of the spring, enough so the foil is always in contact with the contact as well as the housing wall around the spring. Put the delrin piece back in and give the button a couple of pushes, it may take a few to squish the foil in a permissive shape to allow the contact to move freely, but yeah ever since its been hitting like a champ. Hope this helps as it has definitely worked for me.
