My trigger switch keeps breaking on my coilgun please help, how do i fix it? Answered

i am not sure what rhe joules and what not are, i have 4x caps with 420V and 100uF and 1x cap with 330V and 120uF. the gun works fine, i have 6 layers of 22 gauge coilabout an inch long. i have gone through 1 momentary button, 1 small switch and one big high voltage switch for the trigger. what do i neecd to do to make my triggers last. i think they are melting inside. too many amps? how do i fix this. before they break they smell bad and have late trigger reaction.

Your trigger switch should not be routing power directly through it for this application.

Instead, the switch should be low voltage, low current, and it's purpose would be actuating a secondary relay, fet, or similar to switch actual coil power.

My guess, over-current, although it the voltage is high enough, it might be that you're exceeding the voltage rating, either on initiation or via kickback.
