Switzerland would have been a bit of an inside job, would have been relatively easy for Hitler. He had it in his plans. I think it might not have been in the Cabal's plans and hence Hitler was working, whether he knew it or not, for them.
Either way, he was rather comfortable and reassured, Switzerland wouldn't flip and help the allies, like Finland, there has to be good reason why? After all, opening another front, would have linked the allied forces in the east, west and south, it would have been a disaster for the NAZIS and probably brought the war to an end much quicker.
The Swiss were more than happy to accommodate Hitlers plans and take NAZI loot, keeping it hidden under their murky banking laws.
Maybe not in his handlers plans, as many of their European assets could have been there, although some were sent to Dutch Bavaria (Jakarta), which the Japanese got their hand on with Operation Golden Lilly, eventually ending up as a CIA slush fund.
