12volt Muti-Pad Launch Controller

[Flash]

Here's a simpler version using only 1 LED for continuity confirmation. Or you can replace the LED with a 5 volt beeper.
For the battery I would suggest a 3 Cell Lipo rated 2000ma with a discharge of at least 10C.
S1,S2 and the Fire Button should be rated at 15 amps minimum. For the Pad select switches 5 amps would be sufficient.
And don't think I didn't notice the switches, LEDs and resistors were copied from one of my previous post.

yep On the copy, don’t have a free circuit drawing program. Have to use MS paint. Lol

Nothing wrong with Paint, I use that for my circuit drawings and making pc boards. I keep a file with all kinds of component symbols and just copy and paste as needed.
