Marv,
That
makes real senses. They are enable switches and are used to turn on the injector
banks. Really like the logic and easy to grasp. On normal use
switch the primary and secondary injectors on. In case or roughness check by
alternating between them. That's the same thinking as with the mag switches on
the Lycomings and Continentals.
Still
use the same training everyone received, so go for it guys.

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 to me the easiest
solution is to stop thinking in terms of disabling the injectors (basically an
inverse function) and to simply consider these switches and their functions in
the normal sense by calling them "Injectors Primary" and "Injectors Secondary"
and labelling them "on" above the switches and "off" below.
That's my 2c.

Mike, I believe the
