Does this end cap with switch fit the STS1102rv1 pump motor? I wish tech support had mentioned this part when I bought my pump motor!
Hi, Rod. Yes, this is the correct End Cap w/ Toggle Switch for the STS1102RV1 motor.
Per your instructions for 1011431-001, step #1, there was no black lead from the toggle to discard and there is no yellow lead from the toggle for step #4.
The wiring instructions we have for the End Cover Switch Assembly (1011431-001) part # 5271-83 are directly from the MFG. I would contact A.O. Smith/Century if you need further instruction (800) 262-6484.

After receiving a 2-Speed motor, I realized that the only ways to actually use the two speed capabilities was to install another timer unit or a manual switch. The switch was much more cost effective.
I am an avid DIY'r and have no problems digging into electrical as long as I get sufficient accurate information. This switch intimidated me a little, but I found complete step-by-step installation instructions on InyoPools.com.
I printed them out, took them to my workbench and followed them exactly. They were VERY clear and easy to follow. Before long, I had a fully functioning 2-Speed motor. Thank you InyoPools.
Btw, I also rebuilt my Hayward Super II pump and my Baracuda MX8 pool sweep using the same resources. InyoPools - you are awesome.
