Switzerland.

230 V · 50 Hz on Type J, Type C.

Switzerland runs its own slim three-pin Type J socket at 230 V, 50 Hz. Flat two-pin europlugs fit fine, so phone chargers from anywhere in Europe work — but the fatter earthed Schuko plug does not fit the recessed Swiss outlet, catching many EU travellers off guard. Pack a Swiss adapter for anything with an earth pin.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
