Hall Effect sensors

I read an article about a guy using these as a limit switch, here it is:
http://www.balbots.com/article_info.php?articles_id=10

I am having a difficult finding a mechanical limit switch for my needs, and its not worth buying optical. So these seem attractive at $1.04 at Digikey.

My question is, would these be wired in just as a regular limit switch where it is normally Open or normally closed?
Or is there something more......?

The only Hall effects I have ever messed with have been distributor triggers in cars. So I looked around. The one the guy lists looks like it is meant to be tripped with a permanant magnet and it is just a switch, but I could not find whether it is normal open or closed(Wihtout openeing a big pdf)

It needs Vcc and ground which an electromechanical switch doesn't require, and obviously a magnetic target. Looking at the data sheet, Vcc can be a fairly wide range. Other than that, you would use it pretty much as you would use a switch.

It is really refreshing when you have a sore throat.
