[sdiy] Socket schematic symbol question

[Ben Lincoln]

Would you see something like either of these designs used in the TRS 
connectors for the inserts on a mixing board, or would those have break 
connections on more than one of the pins?

Alternately, are one or both how (some?) guitar pedal manufacturers wire 
up the input jack so that the pedal is powered off when nothing is 
connected? I would think those would use mono connectors, but maybe some 
manufacturers use stereo jacks for some reason?
