Mistake proofing is a technique used in production systems. It's a way to minimize errors. (A common mistake proofing example: you can't put your AT car into gear unless you have your foot on the brake. Modern cars use a number of mistake proofing items to help us not make errors.) One of the ways I've applied the concept in rocketry is to use different electrical connectors for the drogue and main charges. The 4 wire connector to attach the 2 mains charges (1+1 for redundancy) uses a male connector whereas the one to attach to the 2 drogue charges uses a 4 wire female connector. My safe switch connections are also set up differently for the redundant altimeters and are of a different connector (2 wire) type, again using female for one and male for the other. With these connectors set up this way, there is only one way to hook them up thereby eliminating the possibility of having an altimeter fire the wrong charge.
