Does anyone know where I can find the safety codes so that I can make my own ignition system? I'm mostly concerned about the rules for a safety key.
The NAR rules were almost certainly written from the experience of people who used launchers with physically removeable interlocks. They were written in such a way that they don't require it, but people will probably expect it. They may question you as to what happens if the switch sticks. And spring loaded ignitions switches do stick. However, dollars to donuts says they don't stick as often as people forget to remove the interlock key.Originally posted by rocketsonly
Ignition System. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the "off" position when released.
So am I allowed to use the key switches in automobiles that close the circuite when turned, but spring back to the open position when the key is not twisted?

It's funny that that doesn't say anything about "switch" or "removable" for the interlock. If your battery or leads to your battery are detachable close to the controller, that's an interlock in series with the launch switch.

One nice safety feature of some of the systems I've used a local club launches is a "armed" buzzer out at the launch pad itself. When the master "arm" key is turned at the control box, it turns on a buzzer out there that lets us know that the system is hot. Been a few ocassions when an over zealous launcher forgets to let others get away from the pads before arming the system, and that buzzer was what prompted us to yell at them to "DISARM THE LAUNCHER!!!"
