Hello,
I've been trying to track down what switches are used in the Logitech MX Ergo. I have been pretty lucky with my mx 570, but after about 3 years of use the cheap switches logitech used are failing. I will probably replace them as outlined in the video below, but I'm curious if anyone has popped open the MX Ergo and seen what switches are inside.
Stuff from the video:
Logitech Mouse Trackman M570 Trackball Repair - Left Click Problem
Infamous left / right / middle button click problem for logitech M570. I know for some people, M570 works fine. But those of us with one from the unlucky batch, M570 has been giving us unwanted headaches.
anyway, hope this video helps
Switch part numbers:
Left/Right buttons: Omron D2F-01F (Japanese made). not to be confused with Chinese made D2FC-F-7N
D2FG-F-7N. The parts are different. Japanese omron's leaf spring is made of different material and is a 2 piece leaf spring. Chinese omrons and m570's switches are one piece leaf spring.
Middle button: Omron BF3-1000 (tactile switch 6x6x4.3mm)
