I am not sure I am following you. If Swiss National Bank prints more currency their currency becomes devalued. Yes, they can buy US Dollars with their newly printed currency but at a higher price than before the printing.
Also the U.S. government just stopped printing more currency of their own. China has been doing the same. I'm not really seeing how printing money is manipulation. I think your analysis has a lot of missing parts.
The Swiss were trying to make their currency devalued. It was rising too fast because the rest of the world was buying it as a safe haven.
