Hello, @BryceK
You can order through my website here:

On the ON/OFF switch product page I also have a video on how to make your own. In the links in the description of said video are places to buy your tools and materials.
You can buy wired and sleeved switches from other sources too, although I'm not sure if they are fully wired but rather they use spade type connectors.
Peace.
Hi Josh, how long would it take to ship to the Netherlands? Since I can't really do anything with my case if I can't start it...
