Could you please provide more picture of the B mini ?
And how to fix the broken sw, im dont have solder here ![Sad :(](https://cdn.geekhack.org/Smileys/solosmileys/sad.gif)
There is a post just above this that I put a link to more pictures.
But it is easily fixed with a quick desolder and resolder.
I was able to get the switch to work temporarily by using a hair dryer on medium heat to expand the solder joints.
