You might check out automotive switches, since many will be made to work with DC, specifically 12V. Head over to Napa Auto Parts, AutoZone, or other local shop.
Even Radio Shack does have some high-amperage rated switches. Not sure about the size, as it says uses a 7/16" hole, but
this Lighted SPST Rocker Switch is only $3.99 and rated to 30A.
thanks for the info...i'll stop by radio shack and check it out...7/16" might work - otherwise i can use my trusty 'goop'...ken
