Switchology and safety, was Infinity Aero Grip and Starter Switch
Some thoughts on switchology-
My once a flight switches (IGN, starter, batteries, lights, pitot heat) are
on the right edge on my panel (tandem cockpit), my frequently used and Oh
Crap switches (fuel pump, flaps, trim master, A/P arm, OVM reset) are on
the left edge of the panel, conveniently close to the throttle. The rear
stick has trim and PTT switches, the front stick has trim, PTT, EFIS
display advance, and A/P disconnect. One of the Oh Crap switches is a
progressive that controls trim function. Up has both stick's trim
functions live, center interrupts the rear stick trim switches ground, and
down interrupts both sticks trim switches ground paths. This way, I can pre
-emptively kill the trim function for the rear seat should I have a
non-savvy passenger as well as killing the whole system if I have a trim
runaway.
FWIW, YMMV, ETC....

Subject: | lengthening wires |
I am having second thoughts about the future nightmare I may have created
by choosing screw terminal switches with their tiny screws and washers for
my panel.
I have already completed most of the wiring with ring terminal ends, and
there is not enough slack to just cut them off and replace them with fast
on terminals.
I don't consider completely re-doing all the wiring to be a very attractive
option.
My options seem to be:
1. just stick with what I have, ring terminals, screw connections to
switches
2. cut off the terminals, butt splice on enough wire to allow for re-doing
the ends with fast on terminals
3. come up with some other way of extending the wires, leaving the ring
terminals intact, replacing the butt splice with some other type of
connection to extend the wires
If I were to stick with what I have, the one good thing is that I will have
better access to the back side of the panel than most have. But without
doubt if I were doing it over I would use fast ons. So I'm trying to decide
if it's worth it to introduce butt splices to all the wires for the
convenience of fast on terminals?
My instincts are telling me to just go with what I have, as many airplanes
have flown with switches that use screw terminals. But I sure wish that I
had just used fast ons to begin with.

The screw in terminals arr what. is provided with MIL spec switches.
If you have a EFIS screen then just remove the screen and then you will
have a big hole to reach through... that is my strategy.

Subject: | lengthening wires |
My vote would be to stay with what you've got. If you need to replace a
terminal in the future, you will have to splice or slightly reroute the wire
for more length. It is advisable to leave a little service loop (large
radius bend) from the wire loom to the terminal so the terminal can be cut
off several times and still have enough wire length without making the wire
so tight that there is strain at the terminal.
My .00 cents worth.

Ken,
Personally, I=99d stick with the screw and ring since that=99s
how you are set up. They are a bit of a PITA to fiddly with but once
in and with no strain on the wire they will be fine.
Should you choose to go to the fast-on route you can extend wires neatly
using D-Sub pins & sockets. Use the machined/crimp D-Subs
(http://www.bandc.aero/d-subpin.aspx
<http://www.bandc.aero/d-subpin.aspx> &
http://www.bandc.aero/d-subsocket.aspx
<http://www.bandc.aero/d-subsocket.aspx>). Cut your wire, crimp a plug
onto the wire. Crimp a socket onto your extension wire. Join and cover
with shrink tube and you have a nice, neat, extended wire.
I hope this helps.

and Starter Switch
More food for thought.
I have identical Infinity grips with 25pin D-sub connectors front and
back in my tandem, so that I can swap the sticks if a stick switch
happens to fail. I also fabricated an isolation circuit with two relays
on vero board, controlled from small locking toggle switches on the CB
panel. The front stick functions are wired directly to the output side
of the vero board circuit. The rear stick functions can only reach the
output side of the vero board if the relays are closed, bridging some
broken copper tracks on the board. I now have the means to provide full
functionality to the rear stick, trim only or nothing at all via two
small switches up front.

The d-sub pins under shrink are fine for
low current, 'service splices' . . . not
unlike the legacy knife splices. But for
permanent extensions of wires up to an
including the 10A class (18AWG) I'd
recommend the Po'Boy's solder sleeve
technique to extend the leads.

Ken,
I tried Bob's Po'Boy's solder sleeve and found it very easy to do. My first
one took just a couple of minutes, and that was with all the fooling around
because it was my first time. I think I could do another in about 60
seconds. Give it a try with a piece of scrap wire.

The d-subs under shrink were a more compact
alternative to the knife spice as a field
service disconnect . . . not so much as a
permanent splice. Further, a mated pair
of pins is MUCH more expensive than the
faux solder sleeve and subject to disconnect
if placed in too much tension.
