The blue switch on the shaver that raises the trimmer and lets you select a moveable or locked cutter position if broke. The shaver would not shut off after I last used it. How can I fix this switch?
Managed to fix it - actually was a 7680. Only do this if you:
1. have a small screwdriver set
2. are handy putting little delicate plastic pieces and springs together again
3. are prepared to face the possibility that you might break the shaver entirely
4. you are out of warranty so you don't care if you invalidate it
THE PROBLEM is caused by a small flat metal assembly that acts as a spring to hold the blue button in place. That is held by 4 small glue posts. The glue breaks down, the flat spring falls out of place and the blue button is no long in the right place.
TO OPEN UP THE SHAVER
a. gently remove the plastic cover around the electrical socket underneath, using a small flathead screwdriver to pry it open
b. the two metallic sides of the shaver can be pulled away starting at the bottom of the shaver
c. uncrew the four screws on the underside of the shaver
d. remove cutter block, battery/lcd block (make sure you don't lose the grommet around the lcd display
e. pull the spring and little plastic latch off the underside of the switch, make sure you remember how to put it back (took me almost 20 mins to figure out how to get that back afterwards)
f. slide the switch all the way up and pull it off the slide - you might need a little gentle force and a flathead screwdriver to coax it off - be careful you don't break anything here
g. remove the trimmer from the rest of the switch
h. put the blue piece back in place (mine had fallen out), then glue the flat metal spring back in place. I smeared brush-on crazy glue on the flat surfaces to hold it in place, I would imagine a four drops of reasonably strong glue on each of the glue posts would work best. Wait for the glue to dry and achieve strength.
i. slide the trimmer back into place, then the plastic latch and spring - this is the tricky part. Make sure the switch can slide on/off in all positions properly.
j. put the display/battery & cutter block back in place. put the back of the shaver on, hold the shaver together with your fingers and test the switch works in all positions without jamming. If so put the four screws back, followed by the metallic sides followed by the plastic cover of the electrical socket.
GOOD LUCK!!

Thanks ,very helpful.
Let me just add a vital bit of information
On removing front assembly, to remove sliding switch and access spring clip under blue button you have to release locking clip (it's like a long sprung piece of plastic) from LH side by just pushing it to the right with a fine screwdriver etc. It's concealed under another piece of plastic.
I also removed inward facig lug on shaver body (under slider) as this snags the metal spring when refixed

You can't turn it off because the clip became loose behind the blue button.
Let it run down the battery and then try and follow the steps here to fix it.

Use your cellphone to take a bunch of pictures as you take it apart. It can be tricky putting the little arm and rotating cam back in if you don't have pictures to guide you.
When gluing the metal springy piece back down I used epoxy and a little spring clamp to make sure it was flat against the inside wall. It can't stick up even a little bit.
If it binds in the future, I'm going to try pulling the blue button and spring off entirely. It may be trickier to keep turned off, or in trim mode but it may be useable.
I had already made the repair by eliminating the blue button prijor to receiving this solution. The switch moves fine but doesn't lock in position so If I travel I have to make sure to secure it in the off position.
