I see you point, Marv
Typically, I revered to what little I know and
was taught in the Military - UP is ON and DOWN is OFF. I
remember when I flew B-52's as the Electronic Warfare Office, I had more
switches than anyone else - dozens - and ALL with all but one switch "UP"
was ON. However, the chaff dispensing hopper was just the opposite.
Our Bomb Wing once got an Unsatisfactory grade on the Electronic Warfare
portion of an ORI (Operational Readiness inspection) - because a
brand new guy failed to dispense the required amount of chaff - in fact, he
dispensed none, because - you got it! - He placed the chaff dispensing
switch to UP.
So despite the nomenclature given as "Injector Disable"
switches -- In my mind they become "Injector Enable" Switches so that
"Enable" is "UP" is "ON" and my mind is happy.
But, I do see you point.

I dunno, Ed.. I think the real
issue is one of nomenclature. The property we typically try to control
with a switch is the provision of power to a specific device. In this
instance, however, the effect that has been named (ie, to disable the
injectors) requires an inverted result from a power perspective to achieve the
named function. It is no wonder that one would assume that you need to
throw the switch upward to "turn on" the disable function. If you look
at it a different way, if the name of the function doubled as the "on"
indicator, then placing the names above the switches would serve both
pruposes... in the case of disabling the injectors, flipping the switch upward
would, in fact, disable them. However, in the wiring behind the panel
that switch would have to be wired to only allow power through itself when in
the down, ie, the "not disabled", position. Seems t """
