Subject: AeroElectric-List: Switch guards, switch locks, locking
switches?
My project is an all electric bird (Velocity SE) with a rotary engine.
Since if I loose power things get quite I am using Bob's duel
alternator/duel battery set up. What I am curious about is the switches
in the cabin. Currently I have all the switches up high on the panel a
bit right of center towards the co-pilot position. I hope to not have a
passanger who would inadvertanlty flip a switch down and off, HOWEVER,
you never know what may get tangled or a stray move may flip a
switch....in my set up, if my coil switch or primary injectors get
switched off I will start sweating. Also, I don't really mind the
switches where they are, but I do have a couple of other places I would
like them, but I placed them here as to minimize being bumped.

I'm looking for information about connecting two shielded wires
together.
Example inputs from other sources to a PMA 8000 audio panel:
Should the shields be butt spliced along with the other wires into a one
big
mess?
Should all wires and shields be connected with Sub D connectors?
Should the shields be left cut and unattached?
Are there other methods?
Thanks in advance for any input.

I mentioned this to a friend he said that HE had "parts that left the solar

I call the half-loop guards NASA X-plane guards, but they were also used on many

Without a bit more information, this can have a number of solutions,
but I believe one can safely say regarding microphone lines;
They should be one continuous run from the microphone source, or
jack, to the input of the amplifier. This does not preclude
intermediate connectors and cable segments, but the shield should
remain connected to itself throughout the length, and should not have
connections to other shields or the airframe except at a single
point, the input to the amplifier at the audio panel/intercom.
A shield cut and unattached at either end is no longer a shield.

Slight correction to John's comment below. The switches behind the
clear plastic spring-loaded doors are push-button switches, not
rocker. They are SPST, and so have limited application. However,
I'm using them for my ignition switches, one left and one right on a
Z-14 architecture. But they are indeed way-cool!
Best Regards,
Steve Thomas

Chris,
<<aviation locking toggles from ebay, but they are kinda small
and may not be up for the task (but at $13.00..>>
Mouser (mouser.com) has medium capacity locking toggle switches
at reasonable cost. For example their NKK SPST (633-S1AL-RO) is
rated at 20 amps DC for $10.25. I like the looks of the handle
on this switch. Mouser gives excellent service and they don't
mind small orders.

Hello,
As an omnidirectional antenna radiates at right angle, a belly bent whip
antenna should radiate in a plan at right angle of the aircraft longitudinal
axis. Hence the range should be very limited compared to a vertical
antenna...
Does somebody know if this is the case or not ?
Thanks in advance for your science :-)

Bent belly whip antenna is slightly compromised in the vertical polarization
plane for com signals but hardly a noticeable difference from a straight
whip.

I'm interested in the locking toggles. I looked at Mouser and NKK and can't
tell how they lock/unlock ( I'm guessing pull out) and if they lock in one
or both positions.
Appreciate any info.

Pull handle out, move to desired position, release. They lock in
all positions (two for on-none-on or on-none-off and three for
on-off-on).

Bent or sloping whip makes virtually no difference. The ground plane is still flat,
the magnetic component of the radiated field is caused by current flow, most
of which occurs in the first third of the whip, so this portion is the area
to leave straight.

You can be sure anything painted red or with obvious guards will be tested by your
passengers! Mixture controls in Cessnas are a favourite target.
I would go for the purple or blue "missile switches" although the genuine MS25224-1
I used to control a turbine are nicer to look at and handle.
The flip covers referred to are probably Honeywell push switches, we have loads
of them at work, they have a stack of microswitches operated by a paddlewheel
from the pushbutton. Trouble is, if the illumination lights fail, its hard to
tell if they are set to on or off position.

Subject: | Landing Taxi lights wig wag |
I had a problem today that I cannot solve.
I hooked up the landing and taxi lights through a SSF1 flasher
according to one of Bobs diagrams
The system uses 2 2-10 switches with middle position for wig wag.
The lights are Duckworth 100 watt with the wire from the lamps going
to ground on the last rib along with the grounds for the nav lights
Connected a battery to the main buss and forest of grounds.
The landing light works but the taxi light fuse (7.5A) blew and the
flasher did not work
I removed the wires from the flasher and again the landing light
worked and the taxi light fuse blew.
I reversed the wires at the taxi light with the light filament wire
now going to the switch and the light housing wire going to ground.
The reversed filament wire was connected the the switch wire with a
clip wire and the ground wire was connected to gnd point without the
nav ground.
Everything worked- Taxi-Landing light and wig-wag
I then connected the wires for final connection using knife splices
and a ring terminal for the ground.
Hooked the battery back up and nothing works not even the landing
light. The fuses are not blown, the panel instruments and nav lights
work.
The flasher buzzes when the landing light is off and the Taxi light
switch moves through the middle position.
The only difference was hooking the nav ground back up at the same
time. I don't have enough knowledge to know if this could cause the
problem.
Thanks for any advice or information
