Hi and welcome,
short answer: with the model01 it is not possible to change the switches. BUT: you can change the enterior of the Matias switches. There is a thread here, where someone posted a good explanation on howto change the switch mechanisms without changing the whole switch. I did that too, because:
- the Matias clicky switches in my keyboardio Model 01 started failing
- I wanted to try linear switches
So, I replaced the keyswitch “internals” about 3 times (clicky to linear back to silent tactile).
IF you want to do that, be prepared that it is dangerous - if you break a switch, you’d have to desolder it and replace it. And it is really taking a while.
The other option: Pre-Order a model-100, that one has swappable switches!
