These are serial images from the manufacturer, which is why keyboards often have the same images in different layouts.

A comparison with the German keyboard layout clearly shows the differences between the keyboard layouts. For example, the @ sign is not on the Q key but on the 2 key and there is no ß to the right of the number key 0.

The Swiss keyboard layouts also differ from one another, as the software has both a German-Swiss and a French-Swiss setting, which either display the umlauts ä, ö and ü, which are common in German, or the French letters é, à and è.
