Rather than Zürich, you might consider spending some time in the Berner Oberland. The scenery is absolutely incredible and there are some spectacular mountain lifts such as the ride to the Schilthorn and Piz Gloria, which is a revolving restaurant at 10,000 feet on top of a mountain. It's where the James Bond movie On Her Majesty's Secret Service was partially filmed a number of years ago. There's also the Jungfraujoch, which involves a trip to the highest rail station in Europe, on a railway line that was started in the late 1800's. Another location in that area is the beautiful city of Lucerne, and from there you can take a trip on a boat, then a very steep funicular to the top of Mt. Pilatus, and then travel down by two cable cars. The views from there are spectacular!
If you're not already using it, you might find it helpful to have a look at the Rick Steves Switzerland guidebook, as there's a lot of good information there.
Be sure to budget accordingly as Switzerland is very expensive!
