Logitech Signature M650 left click not working

Why is the left click on my Logitech Signature M650 mouse not working properly? I have to press it harder than usual or force click for it to register. What could be causing this, and how can I fix it?

Yup, same problem. Disassembled it. Tried to directly press the button underneath slightly, which is just right for my use - doesn't register. Have to press it harder. The disassembly process is just like M550 (on Youtube), but be careful of the extra twisted wire for LED on the top shell on the M650.

So far, finding the switch for the 'SW1' has been unfruitful. Will update if I find anything.
