Need help with trunk lid locking

[traxer]

I'm working with trunk locking of my 2005 Mazda 3. I disassembled the key cylinder to make sure all switches are all right.
I noticed that push switch/microswitch is not making any contact with the cylinder button. I couldn't find any diagram about the key cylinder.
Is there something missing from the assembly? How pushing the button can contact the switch?
