Can anyone help me find a source for a DPDT switch that will handle 300VDC@30mA per contact? I've looked in most catalogs and have found nothing. Help!

HVDC switch
Tks for the hint, but I've seen no 300VDC relays listed on by any of the major small parts suppliers, such as Mouser, Digikey, Allied, etc., or on the net. If anyone knows of a source, pse let me know.

The Omron G2RL series can switch 300mA at 300VDC.

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,
