Switzerland Travel Essentials
Everything practical you need before you go — power plugs, voltage, a quick adapter check, tap-water safety, emergency numbers and tipping for Switzerland.
⚡ Do you need a plug adapter?

Tap waterTap water is safe to drink throughout Geneva — locals drink it straight from the tap, and it’s largely sourced from the lake and underground aquifers, so it’s some of the best-tasting water in Europe

TippingService is included by law in every bill in Switzerland; rounding up is a nice gesture but never required
Good to know
- Switzerland uses Type J & C sockets — recognisable by the small central pin — at 230V / 50Hz.
- European Type C plugs (two round pins) fit Swiss sockets just fine, but Type E/F "Schuko" plugs are too wide and won’t go in — a simple plug adapter is all you need, not a voltage converter. Travellers from the UK (Type G) and North America (Types A/B, 120V) will need an adapter too, and North American visitors should also check their devices are dual-voltage (100–240V).
- Emergency services: dial 112 anywhere in Switzerland, or 144 for an ambulance, 117 for police and 118 for the fire brigade. Heading into the mountains? Save 1414 for Rega, the Swiss air rescue service.
