Welcome to the site.

It basicly works by sliding gears back and forth to engage and dis-engage different gears. There are three positions, which engage different gears in each of the three spots. It has to do with how many teeth are on the gears, thereby creating different ratios and different speeds.

I've seen them on e-bay ranging from $40 to $80 bucks.
