Hello kind people of the Internet,
I’m attempting to figure out how perhaps to use a relay shield to control an HOA switch (Hand/Off/Auto switch). Full disclosure: I have zero experience with an HOA switch.
The HOA switch would be controlling the power to a 220V / 440V AC water pump which pulls significant amps and is several hundred horsepower.
An example HOA switch would be perhaps, a Square D Control switch:

I noticed the discussion of the Ada fruit 120v controller (power switch tail 2) [link to Adafruit power switch here] …but need to handle significantly more power than 120V.
Any help/advice would be mucho appreciated…
thanks in advance
