I'm trying to install LED lights in and around my car. Can I use a AC switch in a DC circuit/system? The AC switch is rated as 10A 125V AC / 8A 125V / 4A 250V AC / 1/3 HP 125V AC. I plan on putting the switch between the 12v DC car battery and the 12v DC to 5v 5a DC regulator (which then powers the microcontroller and LEDs). Is this doable and safe?
