Hey everyone, I just bought an Ultralight 2 for my 250u, and I have been searching everywhere for info on what the switch does on the bottom of the AB Gold Mount? I am assuming it's some sort of auto control for the ultralight? Can anyone tell me it's function, and if it works?

Thanks,

Chuck Pullen

That's exactly what it is. Although my switch is on top. It senses the additional current load when the camera goes into record mode and turns on the light. Of course, this only works if the light is plugged into the d-tap on the AB adapter.
