These are all the items inside my SSC P7 electronics stack.
This process is still in the development stage.
I keep finding cooler ways to create a 1400ma/2800ma current limiter for the SSC P7 LED
Update: The cap spacer shown above has now been replaced by the spacer below that has solder points for the Battery+ and Battery-.
I did that because it was too difficult to unsolder the battery hookup wires once the whole stack was soldered together.

Here's an updated photo of the two boards that go on either side of the switch
I made it so you can jumper two large buss wires from one board to the other.
This gives you a nice solid place to solder the battery + and -

The switch board
on2 connects the battery- to board two and gives you 1400ma current limiting
on1 connects the battery- to board one and gives you 2800ma current limiting
on3 passes the battery- to on1, and so both boards are now on at the same time

The center battery+ wire has been added to the switch board

1400ma current limiter boards with the diodes removed on the right board
Both boards get the diodes removed
Holes drilled in both boards for the LED- wire to pass through.
The LED- wire gets soldered and passes through boards two and the LED board

LED+ and LED- wires from the board below come up through the + and - holes.
A bit of heat shrink or wire jacket gets put around the + and - to keep them from shorting out.

Here's the stack without the LED
The whole stack goes inside this assembly.
This assembly fits snug into the main body
