float switch for DT - bracket for overflow

[Detour]

I have a 120DT with two internal overflows - both with 2 1" bulkheads being used for a return and drain. As a precaution, I want to add a float switch to the DT in the overflow (so it's not visible) that in the event my drains aren't keeping up with my return I can turn off my return pump (via Apex).

Any reason to have a float switch in both overflows? And if so, how are they wired so that any one of them trip the switch?

Sources for mounting bracket for the switch? I like the idea of something like this - https://www.thingiverse.com/thing:3932450, but perhaps a magnet mount would be better to be able to adjust the height.

I can’t answer the specific question, but I can bump the thread to see if we can get you some help

Using the breakout box and 2 normally open float switches, wire them in parallel to the same channel, that way if either float closes the breakout box will see it, and you can tell the apex turn turn off return pump.
