Right / Left Click
Mini button

https://techreport.com/forums/viewtopic.php?f=29&t=85256&start=30So it seems that whe could use the Omron one for left / right click and find an alternative for the little one
The one on the Logitech Trackman Wheel are : D2FC-F-7N20(20M)
I find one teardown video but he does not show the switch part.
Have a nice day, hope this help someone.
