There were so many answers to my question, that I thought I would describe the relays I finally used. They are NTE R10-11D10-12 DPDT relays, rated 10A/240V. They are open-frame relays in little plastic cases with plug/solder connections on one side.

I removed the cases and the jumpers that connect the moving arm to the connections; instead, I soldered a thin piece of copper foil directly to the point at the back of the arm where the jumpers had been connected. I used both sets of contacts in parallel. These relays worked at the 1500 watt level with no noticeable sign of heating, so I guess they will be OK.
