That is correct, devices purchased in Switzerland have a 2-year warranty.

I'd send it back to Galaxus, who'll make arrangements with Apple to make the warranty work, which is surprising coming from Apple, because in Europe, the warranty is 2 years.

Apple offers 1 year directly. This means that if you buy a device and it breaks during the 1-year warranty period, you can go directly to the Apple Shop and have it repaired or replaced there. If it breaks after more than a year, you have to take the device back to where it was bought. That's the difference.
