Balanced or unbalanced insert switching?

[ruffrecords]

For some reason when I try to load your schematic into my brain I get a bus error.

The problem I suspect is that the drawing program I am using (Schemeit) does not have a symbol for a TRS jack with switch contacts on both tip and ring. But basically what I am trying to do is as per your drawing except the insert is half normal.

Cheers
