Lipo box mod questions

[conradr10]

I have previously built a near fully mechanical lipo box mod using This switch: HD Push Button Start Switch 60 amp 27 28 30 31 33 35 37 38 39 41 55 Chevy b | eBay and this Lipo: RC Turnigy 4000mAh 2S 30C Hardcase Pack (ROAR APPROVED) | eBay and I'm interested in making another but this time a wood box mod... using this lipo: Turnigy nano-tech Ultimate 6000mah 2S2P 90C Hardcase Lipo Pack (ROAR & BRCA Approved) and hopefully the same switch but it has come to my attention recently that the said switch might arc internally despite me using it well below its rated amp limit 20-30amp or so with no intent of ever going above 40amps as it is simply impratical is using this switch at these amp levels causing internal arcing? should I not use this switch in my next build? Any input is much appreciated!

Why don’t you use a mosfet and you can use any switch ?

Btw , this is something I built some time ago , a fun project but a BIG box

I totally agree. Any switch that could handle that kind of current would be gigantic or its very over rated. Just use a $6 mosfet and your done.
Nice work RuiPreto

Aside from not wanting to do all the soldering... Id like to avoid the voltage drop and increase in internal resistance... I'm trying to stay near fully mechincal also I attach like the this switch its large size is appealing to me... ¯\_(ツ)_/¯ anyway I just want to make sure this switch isn't failing below the surface without my knowledge and possibly endangering me or degrading my box mod into a 60$ eyesore of a paperweight... (my current box is rather ugly... hence my desire to make a new one)

I already have one the switches lol and yes it is huge but I like it ¯\_(ツ)_/¯ this is simply a matter of concern for my safety instead of being recommended to use a moseft and buy a diff switch which I won't like as much lol

id post a picture of mine as it is very similar to yours but I don't currently have a camera to take a picture... out of curiosity what are the dimensions on that box? also your wiring seems a bit odd care to explain?

I found the specs on the button so I'm still feeling pretty confident about it but my real question was wether I should worry about internal arcing leading to the button becoming unusable over time? Data sheet thingy: Item # 24-359, with Silver contacts On Pollak

Not at all , here’s a similar scheme but with 2 parallel 18650

And this are the 1590B Hammond box dimensions

The view deceived me looked like one of the button terminals was empty!! And looks like you used the same box I did for mine it’s just too large for my taste ¯\_(ツ)_/¯ here’s mine:

Is that a single 1s lipo? If it is I hope your not building real low.
