The product images can sometimes differ. However, the unit has a CH layout.

The switch with the "on/off" turns the keyboard on and off. The A on the Capslock normally means that you get the Ö, Ä, Ü with the ö, ä, ü keys when the Caps Lock key is activated. That would be my five raps on the subject.

This is included in the scope of delivery. If you already have one (e.g. from a mouse), the keyboard can be paired with this existing dongle. This way, you do not need several USB dongles.

It requires the USB Logitech Unifying receiver, which is included in the scope of delivery. Lugs for raising are available. Volume buttons are available.

The keyboard is not illuminated. There is no indication in the available information that the keys are illuminated.

The keyboard is not illuminated. There is no indication in the information provided or on the official Logitech website that the K270 is a backlit keyboard.

I use it in the office about 3 days a week and charge the keyboard maybe 1x every two months.

Normally the keyboard comes with a dongle by default but there is no need to install it with it. It is possible in the Logitech Unifying application (advanced button) to set up the new keyboard (pair)

A wired USB or a BT keyboard (HID compatible) should work. The K270 is neither ...

Don't worry, it's a CH keyboard! Logitech does have its headquarters in Switzerland (and is not interested in trivia like correct product images for the insignificant CH market ...). As far as I know, even all the sample pictures of keyboards on Logitech Switzerland's websites are QWERTY ... There is also no dealer here who takes the trouble to illustrate a CH keyboard. At least the sales packaging has a conspicuous red CH sticker incl. Swiss cross.

Thank you very much for pointing this out. A correction request has just been sent.

Economies of scale might be the answer. How many keyboards with öäéà do they make and how many others?

yeah, right!

This is not a problem of the keyboard, but of the software, e.g. in Word under settings.

Hello, No this keyboard only supports one simultaneous connection and this exclusively via the Unifying receiver. A similar keyboard with the desired function would be the K375s: Logitech K375s (Bluetooth, CH, Wireless)

Connects wirelessly to the Logitech Unifying receiver, which plugs into a USB port on the computer. When reading the description, this is explained... Logitech Wireless Keyboard K270 (USB, CH, Wireless) "The Logitech Wireless Keyboard K270 provides a reliable wireless connection - no matter where you use your keyboard. The tiny Logitech Unifying receiver can stay plugged into your notebook all the time - without getting damaged during transport. And the same receiver makes it easy to add more compatible mice or keyboards - no need for a second USB receiver or another USB port. Logitech Advanced 2.4 GHz wireless technology gives you a virtually signal-loss-free connection up to 10 metres away. Wireless range is dependent on usage and environmental conditions."

The surface is made of a "roughened" plastic. Is a bit of both. It is shiny when exposed to direct light.

Yes, it is configured as Switzerland.

This article is the keyboard with US layout. Unfortunately, there was an error in the system and that's why some customers got a different version. We have deleted the wrong version and therefore you should receive the keyboard shown in the picture.

That's already taken care of. It was the Windows settings after all. But (strangely enough) you had to restart several times for the changes to be transferred.
