I omitted the capacitor in parallal to the clipping diodes.Why do you have an arrow going to the right of the switch? The cap is in series with pin 2 and not in parallel.
The 100nF is the coupling capacitor.
The right switch goes to then next stage.
An asymmetrical instead of symmetrical clipping , it is a matter of taste.
There are better reads to find in the web regarding clipping circuits,
I read the most of it in the recent years.
