Thanks. I think those may have been used on older towers. I have them on
my older UST HDX-589MDPL but a newer HDX-572MDPL has Allen Bradley
802T-AP series J, switches marked type 4, 6P & 13. I bought one on ebay
new for about half of UST's asking price. They sell in the range of $80
and up which is why I was wondering how you got yours at that price.

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.

Which kind of limit switch did you buy?

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.
