So, I've replaced my old push button switches with a couple of pull pin switches. But this leads me to a question. The switches powering the altimeters turn on when the pin is pulled out. So off when the pin is in. This makes arming both of my altimeters with one pull pin on the pad, very easy to do.
My question for you guys who use this type of set-up: when I'm prepping the rocket for flight, I have to install the ejection charges with the av-bay out of the rocket. I have the avionics bay closed up and the pin installed when I hook up my eject charges. But when I install the av-bay in the top half of my rocket, I will need to pull the pin out in order to slide the bay into the rocket. But this arms my altimeters with live ejection charges when I'm not at the pad. It's possible to slightly pressurized the av-bay, just sliding it into the rocket as the fit is quite tight. Then when all the holes line up, the bay could de-pressurize. This scares the B-G-bers out of me.
So how do you guys deal with this?
Please see attached photos, the switch set up is the orange thing on the right side:
