I wan't to ad an anti spark switch to my 10s 35a e-longboard. So i stumbled upon the switch made by vedder (https://github.com/vedderb/SparkSwitch). But i wonder why everyone is talking about the amperage of the switch and the voltage but no one mentions the wattage. Even on websites like Flipsky or eSk8 there is no watt specification at all. So my question is: is a switch like this (http://www.hellray.de/shop/#!/eSkateboard-Sparkprotection-Power-Switch-mit-Sicherung/p/59817445/category=15255004) sufficient for my motor that draws 1400w max? Or would i need a version with like 4 FETs (the ones used by eSk8 are rated for max 375w).

Because it doesn't really matter what the wattage is, relative to your system.
If the switch is rated for at least the maximum voltage your system will ever reach (including any regen or charging voltage), *and* it is also continuously rated for at least the maximum current your system will ever draw, then it should work fine on your system.
If it does not say what it's continuous rating is, vs it's peak rating, then you may wish to assume that like many other things, the advertised rating is a peak, and continuous would be half or less of that.
Also remember that some of these may generate significant heat during higher current draws depending on their design, so you may need to keep it out in the airflow like the controller.
