Rocket Engine Trigger

prusaprinters

This is a handheld trigger button for model rockets. A 9-volt battery fits inside and can be wired to a small push switch (12mm square). The top is friction fit to the body.Wire can then be spooled out to the rocket launch pad and connected to the ignitor.I have not tested this yet, but it appears that the engine ignitors require around 2 amps (at a fairly low voltage), which a 9V battery should be able to easily exceed for the few seconds necessary. I used thick speaker wire so as not to cause much voltage drop between trigger and rocket.
