This travel adapter is on the socket side with Schuko (DE) rated for 16A. But the adpater has an internal fuse to limit it to max 10A. This is due to the type 12 plug.

It's quite simple to know what is 16A or not in Switzerland:
- a swiss plug (Type 11/12/15) with round pins is limited to max 10A.
- a swiss socket Type 12/13/15 with round pins is limited to max 10A.

If you need a plug or socket with more then 10A
- socket/plug Type 23 or 25 with square pins
- socket/plug CEE16 or higher

see the following drawing https://www.esti.admin.ch/inhalte...

It is not allowed to use traveladapters for permanent use in Switzerland.
