Hi Nicholas, really not my area of experise but I would start looking at places like Mouser.com http://www.mouser.com/Search/Refine.aspx?Keyword=toggle+switch or Digi-Key http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=1114212&k=toggle%20switch I know it would be quicker and nicer to have the schematic but some companies are just very secretive :) anyway, give it a try and let us know. Good luck
