Project 08 - Digital Hourglass tilt switch issue

I have the same problem, the breadboard just wants to spit it out. I had to skip that project.
Also the intro book only talks about the tilt switch having two pins, not four. As an electronics newbie, I'm a bit lost as to which two pins we're talking about.

From looking at the data sheet eruvanyo posted, would I be correct in reading certain pins are connected no matter the state of the tilt switch, ie. [1 + 2] and [3 + 4] are always going to be closed?
