I do! Though to be honest I've only ever used it as a glorified continuity tester. From what I can tell, the both the left & right switches are closed when the handset is lifted, and open when it's down. Though, just to confirm, the attached image is what I'm supposed to be checking, right?

I have indeed, the only difference is the acoustic shock becoming far less of a problem when it's installed, so it seems to be working correctly.
