Personally, I thought the setup above was fine. But I read about them and I felt like they would work well because the strike itself includes one, I'm assuming, but then I thought that since it included one it would be pointless for another.

I think the striker has a solenoid (electro-magnetic actuator) rather than a relay (solenoid activated electrical switch).

I think a relay would be superfluous. You would typically use a relay (instead of a transistor) if you needed to control AC voltages.

Okay, so no relay!

Now that I've got the circuitry down, I'd like to make sure I'm not missing anything. So, my shopping list...

If there's anything I'm overlooking, or if there's a better site to find it on (I'd like to get it all from the same place, but I know that won't happen), please let me know.

@johnwasser and @PaulS, you guys have been a huge help, thank you.
