That's a tricky one ...

When the closing contacts close before the breaking contacts break, you have to take care of equalization currents that may flow from the power supply to the solar cells or from the solar cells to the power supply. Assuming that one power source will probably have a higher voltage than the other, you could take care of that with a power diode to block the current flow.

When the breaking contacts break before the closing contacts close you may have a short interruption of power to the Raspberry Pi. Thus, the RPi will reboot. Possibly you can use a super capacitor to overcome the short power-not-connected state.

Any DPDT make before break switch should do the trick...but I'd suggest a toggle or rotary rather than a slide, in conjunction with a current limiter.

Hey fellas, this is actually an irrelevant question, but i figured someone might know..
Can anyone suggest a proper switch that would allow me to switch between two power sources on the Raspberry Pi? I need to be able to switch between the actual power supply and the solar panel. This means i need a switch that can open and close two sets of 4 contacts, preferably a slide switch, of the ON/OFF/ON or ON/ON nature. A toggle switch won't do, i need something rather small.
Thanks in advance!

Some more updates.

The metal tube into the shaft has been replicated (only the top part of it, not al the way to the side). The tube is actually 3 beer cans sanded clean, soldered together and repainted :D
Wooden construction is first attempt of a chute container box.
Some decal stickers applied (not all of them yet).

Anyone know where I can find a decal or a (more realistic) metal replica ID plate for the flight data recorder box?
Also still looking for the lap belts with buckles, belts & buckles of the survival kit, and buckles for the parachute risers.
