Are you used to driving on the right?
Swiss mountain pass roads are not dangerous, if you are a well trained driver. The Swiss road design and maintenance and driving philosophy is that, if you don't know how to drive, you should stay off the roads. It is your job to be trained and capable. That includes the ability to reverse yourself ( back down to a turnout) if you meet a Post Bus (or someone else...but Postbuses always have the right of way) on a one way stretch of a one lane alpine road when you are going up, and they are going down.
Thus, all of the alpine pass roads that I have driven have had no guard rails in many places where, in the USA, I would have expected them. That is not too much of an issue, unless you are tired and come upon an unusual situation. Your reflexes take over. If you are used to driving on the "wrong" side of the road, that could be a problem.
The most tiring drive I have ever made in scores of years of driving in many countries ( both sides of the road) is over the Klausen pass form Linthal to Altdorf, in cloudy weather, on the outside of the left hand turns for just 35-40 km, which took well over an hour...maybe 90 minutes.
They are not all like that.. the ones you have mentioned are generally much better roads. But, none of them are trivial.
This map can help you visualize them.
