How does a joy stick work?

I recently bought a bunch of electronic parts off a site named 'electronic goldmine (goldmine-elect,com). One item is a micro joy stick. No docs of course. It has a joy stick and 8 legs to hook up to something. How would I go about testing this device? I tried using a continuity test but nothing happened. Any ideas?

I'd hook up a battery (not more then: 10mA@5VDC) to two of the terminals and test it out with a motor or multimeter by pressing the joystick in different directions. Hook up the negative to the battery's negative terminal and probe with the positive wire on the joystick's terminals (using multimeter).
