Does anyone know where I can purchase a switch that is triggered by an infrared light beam being broken? Something that I could connect to an IPAC in the same way other microswitches connect.

Somthing like this? (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=294&item=3078317192&rd=1&ssPageName=WD1V)

If you mean for detecting coins, you could try here (http://www.oscarcontrols.com/coinswitch) and build one.

Not exactly. I'm looking for something like what you see on a garage door opener. The switch is triggered when the beam of light is broken. Wave your hand through the beam and it acts just like a button being clicked.

What's the actual application for what you're trying to do? You might get some better suggestions.
Otherwise, most alarm parts work in this manner. You could get a PIR (probably get a used one for free if you talked to an alarm installer) and focus a very narrow beam (just use tape inside the lens). Most of these can function as either a Normally Open or Normally Closed switch and use 7
