It is how the switch is wired as to when it is on. You could wire all the
switches to illuminate even if off.

I guess so, but if you could actually see the switches before you turn
them
on, it would eliminate the need to count switches in the dark. I have 14
switches on my panel. The windshield wiper switch is right beside the
horn
switch. If it's drizzling lightly, and I don't want to leave the wipers
on
all the time, I must toggle it on and off periodically and have to count
switches to make sure that I'm not blowing the horn by accident.

I like the idea of an illuminated switch, but still need the actual panel
illuminated as well.

Many of the illuminated switches are only illuminated when they are in
the
"on" position. That doesn't help you find the switch to turn it on.


I think the function is based on the principle that a boater will know
where
the bank of switches is located. After very little time with a boat, one
will
know the general order in which the switches are arranged.
The illuminated switch will confirm that the
circuit completed is the one intended.
