Hi, I have a very similar situation to the one found in the post below:
https://forum.allaboutcircuits.com/threads/float-switch-wiring-w-dpdt-relay.129486/
Please note that as in the case of the original poster of the post above, I have very limited knowledge concerning electronic circuits.
I'm planning to install a float switch to get a pump (220V/2HP) to shut down when it has finished filling a 500 gallon tank. Due to water fluctuation, it is possible that the switch turns on and off repeatably before the water level stabilizes, which could damage the motor. Therefore, I need some form of latching mechanism. After researching the topic, I came up with the following diagram. I based myself on the solution proposed by Dodgydave in the thread linked above, but I'm not sure if I fully understood his answer.
In short, what I wish to know is if my diagram is correct and whether or not there is a simpler/better solution that would meet my requirements. Also, I'm planning to purchase the following items (or similar pieces) to build the system. Would these do the job or are they the wrong parts?
The 220V/12V SPDT? relay:

The 12V/12V SPDT relay (if i was to use a 12V adapter, how much WATT would I need?):

The float switch:

Thank you in advance for your time and your help.
