Max Hauri travel adapter Switzerland T23 plug / Schuko
Something like that. A T13 would suffice T23 is for higher amperes

An adapter is included for the connection to the CH socket. The output of the Fritz!Dect is only two-pole. You need a Schucko male to CH female adapter.

Thank you, Ronny, Max Hauri Reiseadapter Schweiz T23 Stecker / Schuko is on the list, as well as Steffen Adapter Europa - Schweiz (3-Polig, Schuko) or similar, as the last DECT 200 bought from digitec unfortunately did not come with a Schuko-CH adapter. Sunny spring days!
