The first automatic [[telephone exchange]]s were installed by private networks in 1912. By 1917, a semi-automatic exchange had been installed in [[Hottingen (Zürich)|Zürich-Hottingen]].

In 1920, the [[Swiss government]] created the Swiss [[Postal Telegraph and Telephone (Switzerland)|PTT]], combining the country's [[Mail|postal services]] and telegraph and telephone systems into a single, government-controlled entity.<ref>{{Cite web|url=http://www.fundinguniverse.com/company-histories/schweizerische-post-telefon-und-telegrafen-betriebe-history/|title=History of SCHWEIZERISCHE POST-, TELEFON- UND TELEGRAFEN-BETRIEBE – FundingUniverse|website=fundinguniverse.com|language=en|access-date=2017-07-26}}</ref>
