I am working on a rocket for my L2 certification and I'm planning to fly two Eggtimer Quantums, but I'm not sure how exactly to set up switches. Since they have separate terminals for power to the computer and power to the deployment channels, I want to use a common battery for the deployment channels of both Quantums and use a separate power battery to power each altimeter (for a total of three separate batteries). I also want to minimize the number of switches I'll need to use when the rocket is on the rail (to one screw switch).
So here's my current plan, I would like feedback on it so I can tell whether it's a good one and what I should change to improve it.
If I understand correctly, since the altimeters are armed via WiFi after being turned on, it should be safe to turn them on before taking the rocket to the pad and then arm them once the rocket is upright. However I don't want the battery for the charges to be connected until the rocket is upright, so I will use a screw switch, which will stay open until right before I arm the altimeters. This way, that is the only screw switch which I'll have to turn when the rocket is on the pad. I'll then be able to arm the altimeters once everything else is done.
