Right, had my 26 apart earlier, and whilst I'm going to wait until its finished to do the full thead, I did work out how to get the switches out
It is a t
Take the floor tool parking slot out
With a small flatblade screwdriver, lever the power switch out from the front corner, by the catch. One the fronts popped out, pop the back. Be careful though, the plastic is very fragile (mine has a hairline crack in it)
You cant get to it yet though...
Same on the cord rewind pedal side
Undo the 2 torx screws, then wrestle the housing off. I found levering it over the floor tool parking slot location, then popping it up at the bottom corners then pulling it forward and out did it, but eventually
Is just a standard switch from many many other machines!
Hope this helps!
