I just fixed mine.
Open the case and disassemble the front panel from the front panel PCB.
The front panel plastic is ABS ( blah wikipedia.org Acrylonitrile_Butadiene_Styrene )
Get a good ABS/Styrene solvent cement from a hard-core modeling hobby shop, should cost 3-5 dollars US for 2fl oz.
V E R Y C A R E F U L L Y break the remnants of the switch from the front panel,
You can repair the switch itself on a flat glass surface. Use the cement to fuze the bottom of the hinge to the rest of the switch
Fit the switch back to the front panel. ENSURE THE SWITCH WILL NOT BIND.
Read the instructions for the cement.
V E R Y C A R E F U L L Y cement the switch to the front panel. Hold for 30 sec, cure for an hour, then dope the joint again.
Re assemble, and you should be good to go.
