In detail:

The above laws are only the basics. In order to take off a safe and legal drone flight in Switzerland, it is also necessary to have an insurance of at least 1 million CHF. As soon as a drone weighs less than 500 g, only the laws of the nature reserves, the visual line of sight and the restricted zones apply. It is also important to respect the privacy of others, and the same applies to animals. Animals should not be endangered or frightened. Flying in nature reserves is therefore prohibited. These areas are marked in yellow on the FOCA drone map, where you will also find the blue and red zones mentioned above. Blue zones are control areas and red zones are airfields. If you see an airplane outside the red zone, it is the responsibility of the drone owner to avoid it. In addition, there may be additional restrictions in various cantons. In the canton of Geneva, for example, flying at a distance of 300 m from public buildings is not permitted. Of course, it is always assumed that the drone pilot is able to control the drone correctly.

For a simple check of the laws before take-off, the FOCA flight checklist is helpful.

Exceptions:

If you want to fly near an airfield, you have to contact the airfield. Here is a list of all listed airports and their contact persons. For larger airports this is necessary here. If you have a drone that weighs more than 30 kg, you must have it approved and checked by the FOCA. For other approvals in exceptional cases you can inquire here.
