>> I may not end up going this way but one example was from Konstanz to Lausanne via Zurich and Biel - through the Jura. There is one connection at Zurich with a 9 minute change over arriving platform 15 departing platform 31. The second leg is quite long so a new ticket would be relatively expensive. <<
The SBB considers all connection times to be doable. However, if you are not familiar with Zürich Hauptbahnhof (Main Station), 9 minutes might be cutting it a bit fine. Platform 15 is at ground level, and Platform 31 is underground. Platforms are well signposted, but I always find the underground level a bit trickier to navigate than the street level.

>> Other routes I have looked at I have seen connection times as low as 4 minutes which is what triggered the question. <<
4-minute connections will usually be for smaller stations, where you can just go down a ramp, walk a short distance in the subway, then up another ramp - no tricky navigation.
You will sometimes also see 2- minute connections. They will usually be for connections that simply require crossing to the other side of the platform you arrived on.
