Hi, Tom.

I have the TX-472MDP and the limit switches are both Allen-Bradley  
switches, Catalog #802T-AP, series H. They sell for over $100 each at  
US Tower and nearly as much from Allen Bradley, but I was able to  
pick a couple up, new, on eBay for $15 each, including shipping.

These were brand new in the box. Got lucky, I guess.

Your tower is different from mine, but I would think the limit  
switches are the same or nearly so. If you go out to the Allen  
Bradley web site and search for the above part, I think you can find  
a picture in their catalog and see if it's close or not.

Hope this helps.
