Happy New Year Everybody,

I'm looking for the part described above. Current is DC. A good rule of thumb is to assume that the lower the current to activate the relay the better, and the higher the current the relay can switch the better.

A very simplified schematic and functional description is located here:

I've spent hours looking at suppliers' catalogs online, without finding a relay configured the way I want, and so, pinched between panic and despair I am seeking guidance from experts.

Keep safe,
Patrick Bishop

Above item is a DPDT relay, contacts rated at 10 amps.  You can parallel the 2 poles for a 20 amp output.   If that is not enough current, you could use this relay to trigger 2 separate relays.  Only problem is that one of the relays will be energized and drawing current all of the time.  So it depends on your application as to whether or not that is an option.
