I have tried to research this a bit, as I thought I recalled seeing it addressed in an earlier thread, but apparently I am either mistaken or inept.
I have a DPST toggle rated for 20 amps at 240 volts. What is the capacity of this switch at 12 volts? I tried to apply Ohm's Law, as I had a very good estimate of resistance, but I didn't understand the answer. How do they rate a switch if they don't know what the resistance of the circuit will be?
Thanks in advance
