Indeed superglue works great.
Soldering is tricky, heating up the contacts too long will damage the internal plastic part of the bitsnap, but quick soldering works also. I repaired one of my bits by soldering as following:
- turn the bit upside down on a flat surface.
- press down on the board with your finger.
- quickly melt the three soldered connections and the two plastic fixings.
- you can feel the bitsnap move into the right position
- do not melt too long else the bitsnap will be damaged…
- you could combine it with adding superglue in step 1.
Hope this helps, if a bitsnap dies you could apply the grey bitsnaps, I once repaired my slide dimmer, it was crushed under my chair… see “repairing a normal bit” in this forum thread:
