This video is quite short because there's not a lot to say about the circuitry in this LED candle.  But on a plus note it does actually look very good, should get a long run time and is silent - unlike the dancing flame versions.

Now I just have to find a course of the magic component within.

Although these have been about for a few years now, I've stalled with buying one to take apart because they were initially overpriced for what they are. Their claims of being the most realistic candle effect didn't justify them being more expensive than the dancing flame type LED candles. Now they are at a more sensible price I bought a couple and took one apart so we could see what's inside them. It turns out there's not a lot inside. Now I just have to find a source of this newer generation effect LED, as all the ones on eBay are unnatural colours with a lurid pulsing effect. Or maybe just reincarnate an old project which ran a standard warm LED from a PIC microcontroller with a similar effect. I sharpened a glue stick in a pencil sharpener for the flame and drilled a 3mm hole for the LED, and it gave a very similar effect to this one. Mid-play video-adverts are annoying in technical videos, so I don't enable them.

For the humor of it all, I would have loved to see a schematic. :) In all seriousness, how would you diagram a switch that is also the battery contact, or would that not be represented?

You could show it as a switch after the battery. It effectively is.

Shame it wasn't one of the the remote control variety, as I'd like to know what causes them to switch on if accidentally dropped.

Probably the brief battery disconnection and reconnection due to battery movement.
