You might be pleasantly surprised that most sausages/processed meats here in Switzerland appear to be gluten free.
Our son is coeliac, and we've chanced it with the local stuff like wienerli (hot dogs) and cervelat - and he doesn't seem to have had a reaction.
We do read labels avidly and we haven't yet found a processed sausage with added wheat. The only thing I'd say to watch out for is the 'marinaded' meats in the pre-packs, and obviously crumbed stuff is off the menu.
Hey, if you are interested, I do a shopping tour in Zurich - on a saturday morning 10am-12noon. Next one will be in late January. I'm happy to add gluten-free advice for the tour...
