My nemesis switch randomly gets hot while taking a puff wondering if this is a serious issue i pulled the switch apart and was wondering does anyone know what that piece of copper is for?
(and why is it called a rice pin??? did I miss something here?)
It's called a rice pin because it's the size of a grain of rice (and looks like one).![]()

Use 2 magnets and use the locking ring then stand the mod, theres a locking ring for the switch for a reason so you dont put the thing down and autofire it to oblivion.Hi all
I have a similar problem with my Hcigar nemesis clone but I don't think it's the same.
I clearly experienced a short circuit as the whole unit including my protank super heated in an instant when I fired the switch.
This only happened after I replaced the spring with magnets (I used 3 in order to stand the nemesis without autofiring). I tested a couple of times and all was fine. However, I decided to screw the switch a little tighter to the tube (even though it was sufficiently tight already). I then fired it and it instantly shorted.
After checking the battery and making sure it was safe, I removed a magnet so there is only 2. Rechecked and everything is fine again (although it's not sufficient to keep to nemesis from autofiring while standing). However, I tried to recreate the initial fault by further tightening the switch and was able to recreate the same short circuit fault again.
When I had springs I didn't have this issue and was able to over tighten the switch to the tube with no issue.
Is this an inherent problem with using magnets or am I just causing the problem with over tightening the base to the tube?
Just to add, the magnets I use are very brittle having had 2 break already and their diameter only just clears the base's centre tube. The magnets sit under the rice pin rather then around it (maybe this is the problem?)
