Worked great…but here are some tips.
Before ordering…
1) Check/Clean/Change leaf basket and both filters.
2) Check your flow pump.
3) Try this reset: https://www.youtube.com/watch?v=ZETnYFoKOcA
This will also give you tips on how to deal with the tricky connector.

If more than one of these has failed for you:
Make sure to clean/change the leaf basket and filters regularly.
If your flow becomes marginal this switch will constantly toggle on and off.
You likely will not notice this as an error does not appear when this happens briefly.
This toggling causes thousands of tiny sparks inside this switch which eventually leads to a hard failure.

Finally, I added two ball valves on either side of this switch so I could change it without draining the spa.
