Did Germany invade Switzerland in World War 2

A number of European countries declared neutrality in the years before 1939. While this did not save the low countries (Netherlands, Belgium, Luxembourg), both Sweden and Switzerland were preserved as independent countries despite being hemmed in on all sides by pro-Axis countries. Both countries (and also Ireland) adopted an almost Jeffersonian "honest trade with all nations, alliances with none" approach and Switzerland especially has maintained that ideology and is today touted as one of the great neutral powers of the world.

There are many reasons why Switzerland wasn't invaded by Germany. Swiss banks provided a haven for illegal German loot, but the main reason why is that, like the United States, Swiss citizens had a right to bear arms and were famed shooters (one of their national pastimes). Can't remember exactly where I read it now, but Nazi documents showed that Germany wasn't interested in fighting the Swiss population, armed and in mountainous territory - in other words, an invasion would turn into a never-ending guerrilla war. One of the things Germany got right you might say.
