The above switch is the broken switch (note both pins are gone) which was originally for the Space Bar. Note the "35" stamp, I don't know what this means, but it's the only switch that had a number stamped on it.
With the exception of soldering the switch pins, the board is back in one piece. Honestly, I was dreading this, but it wasn't too bad. I had to use the solder sucker frequently so that the switches would fall into place gently, without breaking anymore pins. I have replaced the broken switch on the spacebar, with one of the user-defined switches. So the key to the left of the spacebar, will do nothing, ever, because it has no pins!
