According to my information, this should also be usable in Switzerland. According to the manufacturer's number, it is a model that is also sold by Samsung Switzerland.
As this is a third-party product, you will need to contact the supplier directly for more detailed information. You can go directly to Technik Günstiger here: https://www.technik-guenstiger.de/Kontakt

I would also be interested... do you already know more if it is really a CH version? don't want a DE version for the price
