My butt and lower back are nice and warm again.
I had my camera out, along with the macro lens, but I didn't take any pics.
In fact, as good as the write up is, I only needed the thumbnail pics.
(I forgot I printed out the full-size till I was done) Woops!
At any rate, I had to go completely through Step#4 to get my switch working again.
I probably have a bit too much pressure on the switch (adjusting per step 4),
but I like the positive "clink" it makes when switching it on and off again now.
Your write up is very concise and easy to follow.
About the only thing I'd change is to put an arrow pointing to what you're describing in the pics.
For example, Step#4-Pic#1 could use an arrow pointing at the groove.
Fortunately, my magnifying glass easily found what I was looking for.
