Recently put together my first esk8 using Flipsky’s Dual FSESC4.20 Plus.
Last night I lost power at speed and had to perform a pretty bloody desperate foot break to avoid flying into a busy intersection. Found the antispark ‘pro switch’ in the off position. Brushed it off as a fluke, maybe I hadn’t pushed the button down hard enough, but tonight it happened twice more. Not sure if spring tension in the switch is getting rapidly worse, or due to me riding harder as I get more confident on the board.
Switch is hard mounted(no vibration dampening) to a junction box which is hardmounted to the board, and I’m on traditional urethane wheels(90mm Abec11s) so it’s definitely getting a good amount of vibration on bumpy roads.
Anyone had any luck with opening up the Flipsky switches and replacing or stretching out the spring? Or installing some kind of Oring to reduce vibrations? Or can I just replace it with some kind of toggle switch? Any advice appreciated
I just got a flipsky 4.20 plus , it really sounds like the best thing to do with this switch is to simply unplug it and throw it away and use a loop key?
Actually most antispark switches are like that. It’s because if it’s disconnected you’re leaving the mosfets “floating” somewhere between on and off. It’s how most people blow them. You can replace the switch, but you always need one.
Its a really simple fix. A loop key will not work as direct switch replacement
This type of switch has 3 pins that matter. The others are for the led and can be ignored if you choose.
All common antispark switches have a nc/no layout. It means normally closed/normally open. It also includes a common pin. When the button is pressed in, the current is allowed to flow between the normally open and common pins and the normally closed and common is blocked. When it is turned off it is the opposite, current is now allowed through the NC and Com. side
No matter the position, one side is always turned on when the other is off.
A loopkey can still be used, but the button needs to be permanately on and the loopkey is hooked up to the battery leads as normal.
To find a replacement, just search for a “spdt latching switch” anything matching those keywords will work.
To find a similiar style one, try adding " e switch" or “led push button”
They cost about 3-8usd for a good one. They are even on amazon
Edit: if you look at the bottom of the flipsky switch it will tell you what is nc/no/c in small print. Take note and label the wires so you can replace it correctly. The no/nc can be swapped but the common has to be correct. It can be tested with a multimeter to find them as well
