I have some old (but mint condition) ST23N switches salvaged from a DC-3 audio box that was almost certainly a 28 volt airplane. I want to use them in a 14 volt Stearman restoration. I like them because they have a nice heavy feel, they're made in the USA, and they're from an era when people made stuff to work and to last. They also look nice and "period". Gleaned off the internet I have the switche's max rating of 250 VAC, and the contact load current rating at max rated voltage of 2.0 amps inductive AC, and 5.0 amps resistive. My running of the numbers and adding a fudge factor into it makes me think that 30 amps inductive and 75 amps resistive at 14 volts isn't out of line. Or am I talking out of my butt?
