Product pictures of laptops and keyboards are always illustrations and are practically never shown in the CH layout (not even by the manufacturer. Otherwise they would have to have pictures made for every country and keyboard layout).
However, all products at Digitec are in the CH layout, unless explicitly mentioned otherwise (see specifications). You will receive this keyboard with a CH layout with QWERTZ, large ENTER key and ö/é, ä/à, ü/è as you are used to.
