A number of German-language sourcebooks have been published in Germany. One of them, Chrom & Dioxin contains information about Switzerland, indicating that is divided into a French-speaking and a German-speaking state, joined loosely in a federation. This book has not been translated into English. (Thanks to Joerg Sander for this information).
