Enjoy the scenery,
Enjoy the roads - especially the twisties.
The Swiss are very law abiding and don't like being overtaken. Exactly the opposite of the French, where our french friends will move out of the way, the Swiss will deliberately block you if they can. (At least that is my experience)
Stick to the speed limits in the villages - the speed cops are unforgiving (unless you're a local). Last time I was there, I saw them pull over about 20 cars, and let all the locals go, only booking the tourists.
The white lines and zebra crossings are often 'plastic' especially in town. SO BE CAREFUL IN THE WET.
Ride the mountain passes during the week, and leave them for the local (French, German, Italian and .... Swiss) bikers at the weekends - They are mad, and fast, they know the roads, there are lots of them - your just a tourist - so do some site-seeing at the weekend.
Don't take this as a winge - I love Switzerland. I've been a number of times, and will go back as often as I can. The scenery is fantastic, the air is clean, the place is spotless, incredibly picturesque, and the people are great.
Have a great time.
Cheers
