If you enter Switzerland by car, on a motorway (Autobahn/autoroute/autostrada) you'll have to stop for immigration/customs check. There, you'll see a guy (or a girl) selling vignettes. CHF 40 but surely Euros, maybe even credit card, will be accepted.
If you enter Switzerland by car on another type of road, you can buy the vignette at any petrol/gas station, post office, or newstand near the border.
If you rent a car in Switzerland, it will have the vignette.
