I just received my new enclosure for the BMS but unfortunately it doesn’t include the on/off switch.
I’ll use the anti-spark switch from Flipsky and I need a new button that fit the new enclosure (12mm).
Where I can buy a new one from the EU and what’s the wiring diagram? I noticed that most of those switch are 4+ pin but the Flipsky use it with a 3 pin jst…
With the Anti-spark, do you know if it is a momentary switch or a latching switch?
If so, you can find some easy by typing in Latching/Momentary 12mm switch on Ebay, Amazon, Aliexpress and find which one you like, thats 12mm and circular.
afaik it’s a momentary switch. It need to be 5V, 12V or else?
These are pretty good latching they do various sizes on Ali express I have a few different sizes and colours if you want to buy at cost in the UK.
I think I have that silver one you have.
Measure the diameter of the hole
3v will work. it’s just sending a ‘‘signal’’ to the Antispark telling it to pass the curent through. There’s no real current going through the switch.
that rating is the voltage required for the LED to glow in the switch… has nothing to do with current.
The flipksy smart enhanced one uses 24V. 12mm diameter, just about. I have 1 spare button btw; just missing the JST connector on the end.
But why do you need a new button? The AS comes with one already… one that already fits your enclosure 
Where are you from? If your button is compatibile with my Flipsky anti-spark switch I could buy it for you.
PM me please.
The original one is on another skate 
If you want the LED to work / switch to light up, make sure you get the voltage correct on the new switch. Otherwise the LED may burn up the second you plug it in.
Looks like the Flipsky Anti-spark 3-pin switch has relay power (K+), LED power (L+), and common ground (-). You could get any voltage switch and not hook up the power to the LED. Or get the correct voltage and have it work normally.
Someone else will have to chime in what voltage that anti-spark provides for the LED. Or you can measure it with a multimeter. If it’s this one (Anti spark Switch Smart Enhanced 120A for Electric Skateboard /Ebike/ – FLIPSKY) @Gamer43 might know.
i cut mine off and used my own switch which was a led momentary 3v switch. works exactly like it should 
Good to know, thanks!
All signals are 5V logic level
The LED in the switch needs an integrated resistor.
@edoardoconti
Use these from Adafruit
L+ goes to LED positive, K+ goes to NO (normally open), Ground goes to Common and LED negative
Just received the switch! Again, thank you @rusins!
Can you guys check the switch-side wiring? it’s oks?
Assuming +L means voltage for the light on the flipsky antispark; then yes – red K+, white L+, black is negative L and K. Same red-white-black ordering on the connector.
