There are more differences but they are in the vocabulary. The Swiss use a lot of French words. Velo instead of Fahrrad, Trottoir instead of Bürgersteig, Cheminée instead of Kamin, Porte-Monnaie instead of Brieftasche, Camion instead of Lastkraftwagen, and so on.
The only orthographic difference is not using ß.
