You'r welcome. Wikipedia has a picture available that shows the monophonic
and stereophonic plugs in detail:

http://en.wikipedia.org/wiki/File:Photo-audiojacks.jpg

and

http://en.wikipedia.org/wiki/TRS_connector

From the picture you can see that the second signal terminal (ring) overlaps
with the isolator and the GND terminal of the monophonic version. It depends
upon the mechanical construction of the monophonic jack socket (i.e. the
exact positions of the spring contacts) what will happen. For monophonic
plugs there is much tolerance as e.g. the GND spring can be elsewhere in the
sleeve area and the signal spring has to touch the tip of the plug. If a
stereophonic plug is inserted into a monophonic socket all depends upon the
positions of the springs of the socket relative to the sectors of the plug.
The tip connection is usually no problem. But the position of the GND spring
of the socket decides what will happen if a stereophonic plug is used.
