Yes.
I was taught "." for AND and "+" for OR but in this case the original
poster seemed not to be into Boolean combinatorics so I said ******** to
George B and his antilogical notations. ;)
.... Much like I assume a '5 degrees' rotation of something will be to rotate
it clockwise, unlike the CAD proggers who force the mathematically correct
but massively unfriendly 'anticlockwise'.

Ignore.
It's ********. I missed B+C and they don't make 7 way switches :(

Use three toggle switches, one in series with each switch. Then
parallel all three sets of switches.

Gave us:


You forgot to incorporate switch position status indicators.

An LED array will do nicely.

I'm having another 'thick' week and can't visualise your idea. Any chance of
a small spoon feed? ;).

The description above is wrong. It was all I had util I found the
full description on SEB.

He wants all three switches N.O. in series. Connect a SPST switch
across each of them to diasble that switch's N.O. function by shorting
that switch, or switches out. Then the remining switch or switches will
control the device.
