I use "household" switches for 24vdc.
But they are "T" rated and I looked on the web awhile back and I cannot seem to find "T" rated switches anymore.
They would not be suitable for the OP.
The best switch for high amp disconnect is a mercury filled switch.
But good luck on that...
A snap action disconnect is second best. As the dial is twisted, you can feel the internal spring build up tension. Then it "snaps". The contacts separate faster than a human hand can respond. Crude but effective. The Borg has a 30-amp 5-position dual deck Electro-Switch on the AC. A no-arc connect and disconnect means cleaner make and break for the load as well as the switch.
Military grade switches are great. Finding them isn't.
Cole-Hersee rocker panel switches with silver contacts seemed to last longer than any other brand - but that was decades ago.
