For Switzerland, there is the T12 or also the T23 Fixadapter.
Depending on the power of the appliance, ecofort supplies the correct adapter for each appliance. An appliance with a power of 2400 W must not be fitted with a T12 fixed adapter for the Schuko plug so that it can be connected to the usual socket. The T13 socket (10A) is not designed for this current.
