I'm bridging those two prongs together because I hate having multiple connection points, thus multiple points of resistance. If you don't have a mosfet, the circuit should never need that safety, and if you have a mosfet that fails (closed), that safety is useless. I guess if you regularly forget your batteries plugged, it may be good to use that safety.

Nope. The trigger is already open, so even with batteries plugged nothing happens.
