This isn't that bad of a job. Hardest part is getting a good view and a hand up in there. Remove the electrical connector, and then remove the nut from the back of the brake pedal arm (see image below) to remove the switch. On the reinstall, there may be some adjustment needed, so keep the nuts loose until you'[ve acheived the proper alignment, then tighten them down.
