Jack,
You have to go to an industrial type switch. AC not too bad but breaking a high DC voltage can be hard on the contacts, even at low currents.
Allied carries IDEC "Oiltight" switches that are rated up to 600VDC. You could also try Allen-Bradley, or Cutler-Hammer, or any of the industrial controls manufacturers.
You might think about an interposing relay like jwb suggested.
Have Fun,
