I don't know if this is related or partially answers your question, but there is a one-off tax on blank cassettes, CDs, mp3 players, mobile phones etc, which goes to the SUISA (the collecting society for Swiss songwriters, composers and music publishers), which if I understand/recall correctly was considered to be a pragmatic way to accommodate all sides.
For example, Is it lawful to download music from file-sharing sites? says,
Users of file-sharing sites who do not have such consents are acting unlawfully. The prevailing view, however, is that private downloading in Switzerland does not require the author’s consent – even if the music was unlawfully made available. Since there is no legal precedent so far, the question cannot be conclusively decided (in Germany, for example, it is unlawful to download music files that are «clearly» illegal).
In practice, the question never arises in this form. If you have relatively recent P2P software, the titles on your hard disk automatically become available online. This is illegal and unless you obtain the necessary licences you may be exposing yourself to prosecution.
Here is a reference about what is taxed, in French.
