How to replace the Z's mouse switch

How to replace the Z's mouse switch

Hi all, I don't know if this is allow or not, but I can't find any video showing how to replace the Z's micro switch.
As my Z's middle mouse switch is dying, I took the opportunity to record it and create as a visual reference for future individual should they need to replace a switch as well.

I have basicly ZERO soldering skill, this is the second time I try to solder anything serious. I just watch a bunch of soldering video and try to pick up any skill there, my technique use in this video are most certently wrong in some way and not efficient at all. Try to avoid my mistake if you are inexperienced as me.
