I had this happen myself a few months ago, power switch blew, i took the machine apart took out the power switch, and visited a few local electrical component suppliers, its a standard switch but its 2 stage single throw switch, home depot/Lowe's don't carry this type. ended up going to 3 diff suppliers and finally found a commercial supplier that had it connected the new one and now its fine, works better than the old one ever did. just make sure you bring the broken switch with you when you go to show them, most good suppliers can match it and see if they have one like it in stock.
