Reply to "18 Volt AC Transformer power through 12V DC automotive switches"

I agree with D500 re automotive switches being beefy. Although I wouldn't try to use one for a starter motor (100 amps or more). Perhaps 10A is OK. I only say this because some of today's 10 to 12 Amp power sources.

John - I had a hard time finding a spec sheet for the switches shown but I grabbed this schematic from a similar switch. When the switch is off there ACC terminal is only connected to the LED. The LED is essentially showing the status of the siding.
