Hi all...
what I would like to do is create my next version of a bottom feeder...but this time I want to remove the 10amp micro switch aand replace it with a fully mechanical switch. just a simple firing pin that will attach to the feeder pinon the 510 connector and a push of the firing button will make contact with the pos end of the battery.
if this sounds frighteningly similar to a Reo Grand...its because it is. I think the Grand is a fine device and I wish I owned one. One day, I will....bur I really like the switch design and have some ideas on improvements to make in my own mod.
i need to make sure that the firing pin is very conductive, so would like to use brass. it obviously also has to spring back every time the button is released so it doesnt sag over time and contact the battery when i do not want it to.
can anyone offer a suggestion on what material to make the pin from? will brass be springy enough over time? will spring steel be conductive enough to limit voltage loss?
Ive thought of using steel banding, but its too wide. i can easily get my hands on some narrow 1050 crs, but it wont be spring steel until its been heat treated and im not going into mass production here...just a few one offs.
thanks in advance for the help!
