Hey, don't imply I'm smart enough to join this conversation!
I'm just a dumb structures guy waiting for someone to clarify what the minimum equipment list looks like in order to use a magnetic switch. My interpretation so far is that a magnetic switch does not comply with safety code when used as the only means of switching power to an energetics circuit. Like Groucho, I'm moving away from screw switches to magnetic for *safety* reasons, so it's back to the drawing board for the rocket I'll describe below:
I'm designing a record-attempt minimum diameter rocket with three electronic devices in it - Telemetrum, Easy Mini, and Featherweight Tracker - each switched by a Featherweight magnetic switch and its own battery; Redundant altimeters and redundant trackers.
Due to the high performance nature of the design, I do not want external switches (drag) or extra holes in the airframe (drag), nor do I want to be trying to re-stuff chutes and charges in an extremely volume-limited airframe out at the pad (unecessary risk, "hurry up and rock your rocket so we can launch"). If test flights are successful, then this design was also intended to be the basis for a minimum diameter Level 3 project.
I think the compliant path forward for me will be to use existing airframe vents to poke a mechanical switch and close charge circuits, but keep the magnetics for electronics power. Unfortunately, the limited design space in the nose cone means I will likely have to give up a redundant tracker or altimeter. I'm sure one could argue that it's technically safer to bystanders, but it increases the risk that I do not get my rocket back.
