No. The Federal Office of Public Health (BAG/OFSP) has the information you need.
As of June 3, the last German states (Land Sachsen and Thüringen) are removed from the high-risk list. But the situation can again change and states may be added back.
From a low-risk country/region, you may enter by private vehicle, bike or as a pedestrian without particular conditions. If you take a bus or train, an entry form needs to be filled in. If you are taking a flight, a negative test is also necessary. Exemptions apply for persons coming from border regions, fully vaccinated persons within last six months, persons who recovered from COVID-19 in the past 6 months and other grounds (see the link for more detailed information).
