I think I've found a solution to the broken wafer on the function switch:

   

I designed and printed a reinforcement piece on my 3d printer.  I plan to apply a small amount of epoxy to the inside surfaces of the 'legs' of the piece and slide it onto the wafer.  I still want to come up with a way to apply a little side to side pressure to close the crack while the epoxy sets up.
