are the two circuit lines in a double pole, single throw (DPST) switch electrically isolated? specifically, could I run A/C across one line and D/C across the other?
here's my application.
i have a garage door openers. in the old days, when i would go on a trip, i'd unplug it from the wall so as to prevent the doors from being opened by accidental or intentional remote signals. with my current openers, I have hard-wired the openers, so instead of an A/C plug, there's a SPST switch in the wall to cut power. the issue is there's a battery backup in the unit which is great for power outages,but if i wanted to really kill power to the unit, i have to climb up and disconnect the battery as well. what i'd like to do is run some low-voltage wire from the opener to where the A/C switch is and install a DPST switch so i can cut the A/C and disconnect the battery with one switch.
is this feasible to do?
are there any NEC issue with putting a D/C circuit and an A/C circuit on the same switch (even though the poles should be isolated)?
yes, i know with modern openers and rolling codes, it's highly unlikely that my door could be opened by a rogue transmitter, but i'm old school when it comes to security - no power, no open.
thanks
