What to pack
Plugbert recommends
Type D (Indian 3-pin) adapter
You need a plug adapter. Plugs from Switzerland (Type C and J) don't fit the Type D and G sockets in Sri Lanka. A Type D (Indian 3-pin) adapter fits 1 of the 2 listed socket families there. Socket variants can differ; check the actual outlet and adapter rating.
Tip: a "universal" travel adapter may be useful for several destinations. Check its wall-side plugs, grounding and power limits against your trip.
