The Eurail Select Pass has been renewed. It used to cover 4 countries of choice. It now covers 2, 3 or 4 countries of choice. Practically, this means that two-country passes such as the France-Switzerland Eurail Pass will be discontinued, as you can combine any two countries with the new Select Pass.

There are one-country Eurail passes as well, but not for Switzerland. However, there are plenty of other passes that cover Switzerland: myswissalps.com/ swissrailpasses.
