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 arenātā¦ go to your local auto parts store. Iāve 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 Mouserā¦ 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 thatās 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 priceā¦ but in the end it is just not worth it
TLDR; I designed and specād 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?
Thatās what I have in my setup. Just wondering if itās easier on the switch. This is how Iāve wired it.
Having the XT90s doesnāt change anything from having just a normal connector when youāre 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.
No it wonāt. There will be a spark generated inside the breaker every time he turns it on.
Oh wait sorry i thought the breaker was inbetween the ESC and the xt90 connector. If it was there(esc and xt90) it would prevent
Should I have put the breaker on the other side of the XT90? Would it make a difference?
You should not use this, but I do: http://www.homedepot.com/p/Gardner-Bender-20-Amp-Single-Pole-Toggle-Switch-GSW-11/100030219
I use one of them. Works like a treat
I know thereās not much room on these boards but you could use that 5 amp switch to kick on a 60 to 80a relay. Like how cars high amperage circuits run. Not sure how cost effective it would be
Still the sameā¦ please donāt misinform people. Anywhere you put a breaker, with our without xt90s, if its the last thing you switch on it will generate a spark inside its casing between the contacts. The ONLY way to prevent a spark from occurring is either plugin the XT90s last, using an AntiSpark MOSFET switch, or make your own antispark with a momentary switch and a resistor.
Relays also spark.
Can you answer my PM please?
Use this. WORKS great. http://www.ebay.com/itm/141819688530?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Ok, Im done.
I tried this one, but found it didnāt last long. The bigger version of these that are found on ebay seem to be more robust.
This one is pretty big. DO you have a link to the bigger one? SO far this one works fine.
When you flick the switch on this one it feels a lot beefier. This is what I believe @lowGuido uses on a 6s build. Apparently he has been using for a while without problems.
