Gas fireplace switch question

Hello,

We have a Majestic model 36LDVR gas fireplace on the main floor of our home. It has a switch on the wall, which turns the flames on when switched on. In the colder months, we leave the pilot knob in the "ON" position and only turn it on periodically with the wall switch. I can always see a very small flame in the bottom right corner under the artificial logs when the wall switch is in the off position.
We recently lost power to our entire home in a storm. I noticed that the switch still turned the fireplace flame on without power. My question is: how is this possible with no power? Thanks

That fireplace has a millivolt type burner/ignition system.
That means the entire burner system relies on the heat of the pilot light to run it.
This is a real plus during power failures.

It uses a pilot generator or thermopile to generate near 1volt of power.
That switch is switching 1volt.
If it has a blower..... that will only run with 120v power available.
