Swiss cipher machines

This page provides an overview of cipher machines that were used and/or developed in Switzerland in the period before, during and after WWII. Note that Switzerland was (and is) a neutral country, in which selling to alien countries is less bound by legal restrictions, than in countries with a NATO background, such as Germany, the Netherlands and the United States. Some manufacturers, such as Hagelin, deliberately moved to Switzerland to avoid such limitations.
