Basically, wire the output of the master switch, to the inputs of all of the "slave" switches. This only allows current to the slave switches when the master is on. I can probally take some pictures of the 7 switch panel I built in a couple days if you need a photo.

Actually, that's the
opposite of what I was describing. That's a master off and is in series. This is a master on, in parallel.
On a new note, while this isn't what I was describing before but is something I drew up that's a much more practical setup. One SPTT as a master and as many SPDTs as you want to control stuff with. SPTT pole #1 to the closed pole of the SPDTs, SPTT pole #2 to the open poles of the SPDTs, and pole #3 of the SPTT is unused. This allows the SPTT to be used as a master on (position 1), select (position 2), or master off (position 3) with minimal complexity.

Thread has long been dead, but EDIT:
It does not require diodes. It could be done better with one diode, but what is drawn does not require diodes.
