9V Battery Box w power toggled output+ON LED

The PCB is a latching momentary button circuit using a mosfet. I designed the board to solder directly on the tabs of the battery holder. There are 2 thru-holes for soldering a barrel lead wire and ran through the bottom TailPlate cut out and out the back. I also snapped off the back of the battery holder, though it might not be necessary. In future redesigns, I'll leave it as is.

The Cover plate has round tabs that should be able to twist into the rest of the housing, provide that they are fitted together and reinforced with superglue. This allows the cover to swing open without coming completely detached.
