What r u all using your breakout boxes for?

I have a number of modules beyond the main unit, so plenty of din sockets for break out boxes. It's all trigger switches - mostly standard floats, but four pressure switches as well. I'm a big fan of redundancy, so I use at least two switches per application. Main ATO uses three, backup ATO uses two, level monitors in the sump, ATO reservoir and AWC buckets are another nine, skimmate container uses two, my dosing containers use five, and so on.

Like the redundant approach. I'm using lots of that with solenoids, heaters, etc, didn't think about the floats as well. Thank you.

Yeah, mechanical float/reed switches can and will fail. Also a good idea, IMO, to buy a quality switch. I use the Madison minis.

I managed to leave this Avast pressure "switch" off of my previous post:

You need the "bare wire" Digital Output version of the switch for an Apex BOB.

It isn't cheap, but I think it is the most reliable top-off switch available to us.

Got them off amazon. Madison M8000 full size miniature float switch. I think the name is an oxymoron ...... You can certainly find cheaper ones than $13 per, but I’ve been using them for quite a while and have yet to have one fail. Cannot say that for the other ones I bought all of which got binned.

Avast pressure switches work really well too - have four of them too LOL

Madison makes great switches.

I ultimately settled (2) of the M3326 for my next build. One for high level alarm in the sump and one for low level alarm in the sump.
