Swiss outlets supply the European standard voltage of 220-240V AC – 50Hz. Swiss plugs and wall sockets are shaped rather unusually (see below). The non-grounded European plug with two pins will often fit in a Swiss wall socket. But not all the time as the European prongs are slightly bigger! In most cases you do need an adapter to connect your equipment.


Please note that Switzerland remains with the Swiss franc, usually indicated as CHF. While Switzerland is not part of the European Union and thus is not obliged to convert to the Euro, many prices are nonetheless indicated in euros so that visitors may compare prices. Merchants may accept euros but are not obliged to do so. Change given back to the client will most likely be in Swiss francs.

Leisure and culture

The discovery of Lausanne extends to infinity: visiting museums, walking in parks, gardens or the beautiful quais, excursions on the lake or in the vineyards, sports and cultural activities, wellness and relaxation, shopping and nightlife.
