Variable speed triggers, how do they work?

Exactly, that's why I want to know what kind of speed controller this is, and what kind of components it uses. Here's a picture, it's just one of those triggers for cordless drills.
I know most semi-conductor based electronics don't like overvolting that much, but the thing looks quite rugged and well made so I suspect it may get the job done.
Oh I think those are linear actuated potentiometers. Measure the resistance of the leads with the trigger depressed, and undepresssed. It might be something like a few megaohms undepressed and little to no resistance fully depressed. That way you can directly control the voltage going to the motor.
As for voltage, it probably won't care too much.
