I'm trying to put together a quick a dirty EM disk launcher. I have 3 large electrolytic capacitors in parallel with a large SCR for switching. I'm trying to come up with an easy way to manually trigger the device. I did try just connecting the anode to the gate through an appropriately sized current limiting diode. The SCR got fried. After digging into the datasheet a little deeper, I discovered these things use a relativly low voltage to trigger. Lesson learned, all be it an expensive lesson.

This setup will be ran at a voltage range from 30V to 300V+ with several different coils on the output, so creating a triggering circuit wil be difficult to say the least. I was thinking of using a 9 volt batterywith a momentary switch and resistor to trigger the SCR. Will this work, or will I end up blowing the battery up?

I'm using a SanRex PK55GB80 SCR.
