...OK, what does this mean to me?

1UP:

Would this work?



BTW, there's a diode on the gun coil shorted across the two coil leads.  Not sure what this does, but do I still need a diode AFTER the coil (before the relay)?

ErikRuud:

Un-regulated power supplies are often often rated in VA.  The fact that they are un-regulated means that if the current demand goes up, the voltage may go down as the power supply tries meet the demand.

I can find a link to more technical explanation if you want.

OK, did some tinkering, here's what I came up with.



I could only find a solid-state relay that switched AC current using 5VDC.
