Bob,
I have two UST towers. One uses these switches and the other, newer,
one uses Allen Bradley 802T-AP Ser J switches. I bought one new on
eBay for a fraction of what UST wanted.

Thanks for the info on the limit switches. I am going to replace the
ones on my HDX589MDPL.
They still work OK but it they have been there of quite a few years.
A little preventive maintenance...........

I replaced the totally corroded limit switches with the exact same ones
that came with the towers. The towers had been laying horizontal for
several years, and water had gotten inside the limit switch body.
They are GE CR115LB1 with 1NO - 1NC contacts and 1/2 inch npt fitting.
They are marked type 1,4,13, A600 P300.

I have two US Tower HDX-589MDPL towers. When I purchased them, both
control boxes on the towers were extremely rusted inside and in
terrible
condition. I started from scratch and built 2 new control boxes
with all
new components. Also, I replaced the cables running from the
control box
to
the limit switches to the motor, and to the 120v power source. (I
also
replaced each motor, as they were in really bad condition and
locked up).
I enclosed each of these cables in flexible conduit with watertight
fittings. I simply used the UST wiring diagram and made mine
exactly like
the original ones. They are very simple and very inexpensive.
I paid around $45 at Home Depot for each metal weatherproof box,
and all
the other components are very cheap. I spent less than $100 total
on each
completed box. They now look and function like new.
One of the limit switches on each tower was completely rusted
inside, so I
replaced them a couple of weeks ago. UST's price on the limit
switches
was
way too high, so I bought 5 of them brand new and in the box from a
surplus
electronics place on the internet. They cost me $35 each.
