Huh? All of your previous photos show the broken switches are Leviton, not LeGrand/Pass & Seymour.I thought I had been installing Leviton Spec Grade but, just checked, it is Legrand Spec Grade.
Are they good and tough?
I have the same Leviton Decora switches in my house (no kids) and they have lasted over 15 years...still looks like new. Those kids are punching them and breaking them due to abuse.
