This is a bit of a difficult question because Switzerland pre-dates the concept of independent sovereign states.
The Swiss confederation was founded in 1291. At that time it was an agreement for mutual self-defence between 4 small mountain cantons (states) within the German empire who wanted to defend themselves from takeover by more powerful states and rulers within the empire.
Over the next few centuries Switzerland grew as new territories joined. It gradually became effectively a group of independent countries, but legally they were all parts of the German Empire.
In 1648, at a peace treaty after the 30 years war, the German Empire finally recognised that the members of the Swiss Confederation were not art of the empire.
