🇸🇱 Sierra Leone to 🇨🇭 SwitzerlandNope, your plugs won't fit. But an adapter will.
No voltage converter needed. Both countries use 230 V.
What to pack
Plugbert recommends
Type C (Europlug) adapter
You need a plug adapter. Plugs from Sierra Leone (Type D and G) don't fit the Type C and J sockets in Switzerland. 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.
