It's 90 days within a 180 day-period in the Schengen area (i.e. excl GB/Ireland). Only to travel, of course, you're not entitled to reside, let alone work, in the EU with a Swiss B permit. Switzerland is not in the EU.

If you want to reside and work in the EU - which you obviously do - apply for an EU permit.

I would also be interested to hear how and where you got a B permit if you are not residing here and have (based on your threads) clearly no interest in doing so.
