switch for a coilgun
what is the minimum amperage rating needed for the fire switch and what will happen if u use something lower, like a 20a light switch? also how much one would cost would be nice to. i have heard that 40 or 50 A will work, but i would like to use something smaller, easyer to find, and more affordable. any help would be nice.

To answer your question I need to know your capacitor bank size and voltage. Preferably with your coil dimensions as well.
On a standard mains rated switch you are limited to about a 74J cap bank @330v, 1360uF. I know because after repeated usage, my 74J coilgun fuses the mains switch shut.

8 photoflash caps in parallel at 120 uF and 330v a piece. although now i have had a regular light switch on it for quite some time and it seems to be working juust fine.

That's only 52J so you'll be fine with any old mains rated switch.

My coil gun has 400J I am using a solid state relay rated for 80A will it work?
