| Subject: | Keyed Master Switch? |
All,
I plan on a PUSH Button Start and Dual Electonic Ignition. Can anyone
help with a method of enabling "key start" access to ignition/power?
I have dual paths to each ignition, so need four switches (to enable
pre-flight checks of each path), so the documented adapted mag key start
switch option won't work.
I can't get fully comfortable with a fully live system being just a flip
of a switch away....... See attached to get the idea.
Best regards,
Andrew Butler

Consider putting a keyed switch in the Push Button Start circuit. If
the key isn't on, the start button doesn't work! One switch does the
trick and it doesn't put another switch (point of failure) in any of
your other critical circuits.
Your ignition systems may be live if their switches are flipped, but
nothing happens without the starter.

Here is a picture of a current limiter from a recent job. It had been
replaced for unknown reasons over a year ago. The installer didn't use a
washer between the limiter terminal tab and the nut. The nut grabbed and
torqued the tab, deformed the ears that are supported by the rivets, and
partially tore the base of the filiment (right word?) After many months the
filiment finally broke. I don't think it was experienceing any particularly
high current load, but from the looks of the mounting terminal, it did see
some pretty rough handling.

Dennis has the right idea, especially in light of all the
emphasis on '2 locks'. My 8A will have a key switch
between the battery and the starter switch. The actual
starter switch will be on the stick, controlling a relay
in the starter circuit.

My plan has been to put a simple toggle switch in the baggage compartment
that disconnects the starter switch. Hopefully this plus a canopy lock will
meet the 2 lock requirement. The baggage compartment will also have a lock.
I wonder how many times I will get all strapped in before I realize I
haven't enabled the starter switch.

Do you plan to put a guard on the switch (or cover) to keep loose items in
the baggage compartment from bumping it? I suppose that in flight you
probably won't have to engage the starter ever should that happen. If you
fly the plane long enough without a guard on that switch, you'll
eventually be in a situation where you can't figure out why you can't
engage the starter - after giving somebody a ride maybe, or trying to
restart after a fuel stop..
Will the switch be in a place where it interferes with loading things into
the baggage compartment? Will you have to unload anything form the
compartment in order to gain access to the switch?

Those are all good considerations, but having it on the starter circuit
rather than ignition makes them a little less critical. The switch guard is
probably pretty important. I would not expect to always use the switch to
disconnect the starter when leaving the airplane, but more for away from
home, overnight -- just one more safeguard, and of course one more point of
possible failure.
I am willing to be convinced that it is not a good idea.

Thank you Dave for sharing that critical information. I will be very
careful when installing the 3 ANLs in my RV-7,
project.

Why not a key switch in a more convenient (in the cockpit somewhere)
location? It doesn't have to be on the panel, maybe tucked away somewhere,
but reasonably easy to access. Then no post strap-in remorse, and if you use
the baggage compartment much at all, I predict you'll be removing or
relocating that switch before long.
If you are in a locked hangar, you probably won't use it unless you're away
from home.
Believe me, you're convenience and ease of use is most important.
