Logitech G700 mouse switch replacement

A pretty common malfunction for this mouse, after years of use, is to have the primary click button not keep the circuit closed when you hold it down. Click + hold sometimes registers as double click. Logitech has a lifetime warranty, but since this model is discontinued, and the newer model they would send (S700s) as a replacement is ugly looking, I decided to replace the problematic switch myself.

There's plenty of replacement Omron switches on ebay. Most mice use the same one, so you can even salvage one from an old unused mouse.

Hi

I just successfully replaced the switches but I had a bit of problems getting the top board off and I think I may have damaged something. After I assembled the mouse all the G buttons connected via the shell of the mouse (G4-G10) don't work. The lights in the shell still work though. Do you know if there is anything specific I may have damaged or which solderings I may have missed on the 14 pin connector?

Everything else on the mouse works fine.

Hi Mads, did you check the cable that goes from the shell to the 4-pin connector on the top PCB?

Hi

Yes, it seems to be fine I don't see any loose wires or anything. It may just be an issue with the software setup that isn't working properly, or maybe I've just now jiggled it correctly to get a connection.
I've just tried some different settings in the new Logitech Gaming software and I seem to be able to get at least some of the buttons to work. I will keep testing.

Thanks a lot for the quick reply though and thanks a lot for the great guide, saved me a lot of money. :)

Happy New Year!

Congrats! sometimes it's the metal leaf spring that stops working. But if all you had to do was replace the plastic button, then that's great!
