If you are going to Switzerland, be aware that conventional European plug adaptors will not fit into Swiss sockets (at least recessed ones, which is all we saw on a recent visit to Geneva). You'll need either an adaptor for your European adaptor (yes, they are a real thing) or one of those fit-everything adaptors.

Two pin plugs from other mainland European countries (the type you get on a phone charger), and two pin adapters DO fit Swiss sockets. The two pins are the same size, length and position.
It is the third (earth) pin which is different. Three pin plugs and adapters are unique to Switzerland.
Yes, most supermarkets (at least near the border) sell D/F --> CH and IT --> CF adapters.
Italian three-pin plugs and sockets are also "unique", French/German 3-pin plugs do not fit Italian sockets.

Yes, the pins themselves (talking about 2-pin plugs) are not the problem; rather it is the molded plastic enclosing the pins. In our Airbnb, and I assume in Switzerland generally, where there is a recess for a plug, there are sharp angles on both sides of the pin holes, so that moldings with rounded sides--i.e., conventional adaptors--do not fit. Of course where there is no recess, there is no problem; and as you say it is easy to find adaptors.

Joel, The angled recess for 2-pin sockets is standard in many countries. The shape is a "squashed hexagon". I have also seen them in Germany and France. If your 2-pin adapter does not fit in the recess, it is not really Europlug-compliant.
The Swiss (and italians) have managed to fit the third earth pin inside the same profile, French and German (Schuko) sickets have a larger recess.

Chris, thanks for the information. I bought my adapters, the ones I'm calling "conventional", from the Rick Steves online store, where they are offered as "continental Europe electrical adapters". Live and learn. Online shoppers, be aware that you may need an adapter for your RS adapter depending on your destination(s).
