Thank you for your input,
jhpadjustable, any "two part" connectors are out of the question due to double PNP price and they usually are higher pin count.
Well, I actually need two 4 pin jumpers, but I can't make one 8pin connector out of them, they must stay in their current locations.
Tim, I was thinking about metal "springs" too, but those are expensive and PNP price for 8 of them will add up in mass.
Nusa, I updated main post – 2 pins up to 1A, rest are logic level, don't think your solution will do with my specs.
Battery connections I found looks promising, but I need plan B and C, so more ideas please
