I'm selling spare silent mouse click switches for Logicool mice. I bought these after my own mouse clicks stopped working, and after following online repair guides, I was able to fix my mouse. I have some extras left over. Two switches successfully repaired the left and right clicks on my mouse. This is a set of 2 switches. Black switches with red buttons, 2-pin configuration. - Type: Switch - Color: Black - Button Color: Red - Pin Count: 2 Thank you for looking.
