These mechanical switch toys allow you to test the actuation force, acoustics, and feel of switches before you buy them or take a part of your board wherever you go to show off to your friends! The housing are made of thick transparent acrylic with transparent keycaps so you can see each different switch side by side! If you’re buying this along side a full board from Avikeebs, select “Empty” if you would like me to fill one of these with the remaining switches left over from your build so you can have a personal fidget toy that matches the sound profile of your board!
