Over and above the regional passes, that Suzanne has linked to, there are also some quite useful free "passes" in certain regions.
The Ticino Ticket offers quite extensive free travel in that region. The Montreux Riviera Card is also quite useful if you are staying around Montreux.
There is a Panorama Card around Interlaken but it's confined to buses.
Most major cities have a card which provides free local transport.
These are all free if you stay at a hotel in the respective area.
Try Google for details.
