If you are entering Switzerland via the land borders there are not normally any passport / ID card checks, as Switzerland and all countries bordering it are members of the Schengen Area.

You can even travel to Switzerland on your national identity card, if you are from a country that issues them. If you are from a non-Schengen/EU country you need a validity of at least 3 months on your passport, and if you need a visa then you also need 2 blank pages on your passport.
