Normally, 60 mins is more than adequate. The flights you mention tend to use the main terminal which includes the piers/gates A, B and D. They belong to the central security zone, and thus require no security checks. Normally, it is only if one of your flights uses the remote terminal, featuring Gates E, that such checks are required, when your arrival is from a safe origin airport.

Next time, why not ask the airline? And check the very ample, very clear information on their website?

You can also track which gates have been used recently by 'your' flights by consulting the arrivals and departures information of both Swiss and Zurich Airport.

These sources are much more reliable than a simple forum as this one.
