Travel Adapter

Are you from Australia? If so, this plug should work.

The “Europlug” works in Switzerland and also in northern Europe.

The schuko plug used throughout northern Europe doesn’t always work in Switzerland

So for example, this Australia to Europe adaptor would not work in Switzerland:

As a Swiss I can say, the adapter you linked to will almost certainly work in most Swiss places on the tourist trail so you should be fine. If you were to find yourself in a very old building or your device needs a three pin plug this it could be a bit challenging as they are different.

Thanks both but they look the same :D. I can't tell the difference. Is it the round plastic around it and the extended hexagon plastic thing thats the differenct?

Will these do?

I was just watching a travel tips video about Swiss travel and the vlogger pointed out that the new style of big cube universal adapters often won't work in CH since outlets can be recessed. Just go to a site like Amazon and buy a set of all the possible Euro adapters so whatever you are faced with, you are ready. They are small and light and don't cost much.

Or, you could wait and buy some upon arrival in the airport.

No. The photo you show has one with a schuko style plug (2 pins in a round plastic base). In your original post, notice the small size of the base where the pins are attached.

Ah okay thank you for that, I understand what to look for now. I was thinking the two pins look identical but its the base thats different.
