Payment with cash in GPB? I'm afraid that won't be possible. And if it is it will be very expensive as they will have to exchange it to Swiss francs. The easiest way is to buy the pass online (see here) and print it yourself. That saves time at the airport.
Please see the "How to use" tab on the Swiss Travel Pass page Lucas linked to. It explains about the validity of the pass.
Note that you need a Swiss Travel Pass, not a SwissPass which is for residents only.
