Swiss Plug/Outlets

I don't recall any Swiss plugs different than any other European plugs. Great Britain has different plugs.

The 2 round pin Type C "Europlug" generally fits the swiss outlets. Our RS Type C Europlug adapter fit but snugly.

My Type F “Schuko plug” grounded 240v iron did not fit the Swiss outlets but the hotels commonly have adaptors to mate the Type F plug to the Swiss Type J with three rounded pins.

Type J plugs have three 4 mm round pins, measuring 19 mm in length.
The centres of the line and neutral prongs are spaced 19 mm apart and
they have 10 mm long insulated sleeves.

Type F:

Type F is similar to C except that it is round and has the addition of
two grounding clips on the side of the plug. The plug has two 4.8 mm
round pins, measuring 19 mm in length on centres spaced 19 mm apart.

Type C:

The plug has two 4 mm round pins, measuring 19 mm in length on centres
spaced 18.6 mm apart at the base and 17.5 mm apart at the tip. The two
pins have 10 mm long insulated sleeves. They converge slightly, but
they are relatively flexible which allows the plug to mate with any
socket that accepts 4.0 – 4.8 mm round contacts on 17.5 – 19 mm
centres.

BTW Switzerland is an advanced society. Our Swiss hotels all had hair dryers in the rooms.

Thanks much. I realize most hotels have hair dryers in the rooms (we have traveled a ton), but they normally suck and take forever to dry if you have super thick hair. I want to be out and exploring as quickly as possible :) That is why I bought an expensive one in Europe.

Swiss sockets accept the same 2-pin plugs as the rest of mainland Europe, so your 2-pin hairdryer would be OK. As per Edgar's photo: https://www.worldstandards.eu/WordPress/wp-content/uploads/electricity-type-C-plug-2-300x119.jpg

But 3-pin plugs are different. They have 3-pins in a triangle. Again Edgar's photo: https://www.worldstandards.eu/WordPress/wp-content/uploads/electricity-type-J-plug-300x128.jpg

DO NOT try to force a "Schuko" plug (as used in Germany, France and Austria) into a Swiss socket. It will not fit and might break the socket: https://www.worldstandards.eu/WordPress/wp-content/uploads/electricity-type-EF-plug-1-249x300.jpg

Italian 3-pin plugs are different again.

"I know I can use a converter for everything else" - What else? If it is 3-pin it will need a plug adaptor specific to Switzerland.

"I realize most hotels have hair dryers in the rooms (we have traveled a ton), but they normally suck" - most haidryers blow, not suck (couldn't resist ☺)

The best resource for questions about Switzerland is myswitzerland.com. I've copied this info from their website:

The voltage in Switzerland, as in most of Europe, is 230V/50 Hz.
Switzerland uses type C (2-pin) and Type J (3-pin) plugs. (Type C 2-pin plugs also fit J sockets.)

Most power sockets are designed for three pin round plugs. The standard continental type plug with two round pins, applied for many electrical travel products, may be used without problem. Adaptors are available in most hotels.

I have an adapter that I have used everywhere I traveled, Iceland, Netherlands, France, Spain, Germany, Austria, Hungary and Czech Republic. That adapter doesn't work in Switzerland. And even if the hotel provides a hair dryer (they usually do) you will need an adapter for phone/camera charging. Sorry I can't provide details, but I will say that each hotel did lend me an adapter that worked.
