NEW YORK, Nov 26 - The U.S. dollar fell more than 1 percent against the Swiss franc on Wednesday amid thin volume heading toward a holiday in the United States and as geopolitical worries outweighed a slew of strong U.S. economic data. Very thin volume exaggerated the magnitude of the dollar's broad descent, said one currency analyst in New York. The dollar fell more than 1 percent against the Swiss franc to session lows around 1.3042 francs .//
