🇧🇱 Saint Barthélemy to 🇨🇭 SwitzerlandHalf yes, half no. Classic.
Some of your plugs fit Switzerland's sockets directly. Grounded or chunkier ones need help.
What to pack
Plugbert recommends
Type C (Europlug) adapter
Some plugs from Saint Barthélemy fit the Type C and J sockets in Switzerland and some don't, so pack an adapter. A Type C (Europlug) adapter fits the listed socket families there. For grounded devices, get a Type J (Swiss) adapter for a compatible grounded outlet instead; it does not fit every listed outlet. Socket variants can differ; check the actual outlet and adapter rating.
For equipment requiring earth, choose a Type J (Swiss) adapter for a compatible grounded outlet. Check its supported inputs and rated load. A two-pin output cannot provide an earth connection.
Tip: a "universal" travel adapter may be useful for several destinations. Check its wall-side plugs, grounding and power limits against your trip.
Voltage & frequency

The destination may use a different frequency (60 → 50 Hz). Check your device's input rating for the local frequency; a plug adapter does not change it.
