New here....
I'm trying to help a few kids in the neighborhood with their Estes model rocket and made a simple launcher for them using a 12v scooter battery, relay, safety switch and launch button.
My question is current limiting. I'm worried that the launch button can get welded to its contacts and draw the full 9 amps through the wiring if the leads to the rocket short out. I notice all the simple controllers don't protect against that. So, short of buying a sophisticated controller, what are other people doing?
Thanks in advance
