@anorak234 fair one 
@Charster10 - We’re working on a new switch with a built in UBEC most people with VESCs won’t need it but doesn’t hurt to add it. Should have a few pins for “lights” as well. But they would “always” be on.
The new switch should be cheaper.
whats so hard about a plug. xt-90s. dont know why people bother making it more complicated. and then it breaks.

@Charster10 the 5 amp limit on that switch is the reason it wouldn’t work. But you can use a switch like that to control a mosfet switch which is pretty easy to make if you can solder. You just need to buy a couple mosfets, a perferated board, a diode, and some resistors.
I’d suggest you get a kit and assemble it yourself if you are on a tight budget. OR build an anti-spark loop key - @anorak234 linked my old one above.
If you look at Ben’s github for his v1.3 anti-spark - price out the BOM. Then consider the PCB… it’s not going to be an inexpensive switch no matter who sells them. Again, you can buy the parts and assemble it yourself, but you also will need some hot-air rework or reflow skill/tools. Ben’s github has the gerber files and it’s a fun little project.
But if you don’t have that skill or tools to reflow SMD - i’d suggest one of the kits from @DeathCookies (especially if you are in Europe), or buy the full switch from @Chaka, or esk8.de, or similar.
HTH - GL!

For sure. Loop key is the easiest.
but it isn’t as cool as LED backlit power switch…
Ultimately it depends how you want your finished board to look. When you are comparing it side by side with a production board like Boosted, Marbel, Evolve… sometimes these small finishing touches are nice to have on DIY. Just think of all the $ you saved vs a production board! Splurging on a cool on/off switch is personal preference.
All i was trying to point out is that these components aren’t cheap, and if someone assembles or carries stock of these - there is a pretty significant investment… so it’s going to cost a bit more (something for their time, rent, CC balance interest…).

Just a Waterproof SPST Switch Off-On with LED is about 25$ on digikey… add to that the mosfets, etc, 40-60$ is cheap.

Considering. Nice build btw!!
Thanks, it’s as cheep as I could get it. Need a different belt, gonna order this weekend. Other than that it came out great.
Dosnt a circuit breaker just serve as a switch and not an antispark switch? There isint anything to prevent a spark (that I am aware of). I am just wondering if it works, as I have not used one before and all ways wondered.
The breaker will spark internally, just like when you connect/disconnect the batteries directly. But they are cheap and easy to replace when they wear out.
They aren’t… go to your local auto parts store. I’ve gotten switches that look almost exactly like the one you linked, that light up, for $5.
They felt overpriced to me too
So I went out and research different designs, selected new components, and generated a BOM at Mouser… Only then do you realize that the components alone cost $10-20 per board depending on current rating. The circuit is simple enough that you can make it on blank circuit board, but if you want a PCB that’s another $10-15. Want a nice SPDT switch? Okay thats another $8. Now factor in the time that takes to solder and test everything. I was going to make one myself because of the price… but in the end it is just not worth it
TLDR; I designed and spec’d out an awesome switch. And still bought a commercially-made one

If you have an anti spark connector and an automotive style circuit breaker switch would that prevent the spark?
That’s what I have in my setup. Just wondering if it’s easier on the switch. This is how I’ve wired it.

Having the XT90s doesn’t change anything from having just a normal connector when you’re using a breaker. The spark gets generated on the last thing to get connected, in this case the breaker.

Short answer: It will prevent it from sparks yes.
