Hi Guys (Bob)
I'm going to incorporate the Perihelion design Wig-Wag (c version) module
Http://www.periheliondesign.com/wigwagmnl.htm
in my landing lights, the call out, wiring diagram 'B' for a single switch is a
DP3T, I'm trying to relate this to 'Table 11-1' (S700 series toggle switches)
is it a 2-10, if so can you help with the connections
John

To the best of my knowledge, the device
depicted does not exist in a toggle switch.
A 2-10 can be wired for SINGLE pole, three
position operation which would need a
couple of diodes added to implement the
'both-on' function in the center with the
OFF being full down.
A 2-1 switch can be used with no added
diodes but the operation would be BOTH (down),
OFF (center) and WIGWAG (up).
I can sketch a schematic for either . . .
your choice.
What kind of landing lights are you installing?

I do not trust switches that depend entirely on rivets to conduct current.
http://www.bandc.aero/toggleswitch-doublepole.aspx
Click on the small pictures on the above website. Notice that the rivets go through
plastic. If that plastic flows over time, the electrical connection could
fail.
The most economical and perhaps easiest to wire switch is a DPDT with center off.
ON-OFF-ON Do NOT buy a switch that has parentheses, for instance (ON)-OFF-ON.
Parentheses indicates a momentary position.
Once you have the switch in hand, it is easy to figure out how to connect it by
using a test light or ohm meter.
DP3T switches are available from electronic parts suppliers like Mouser and Digikey.
https://www.mouser.com/Electromechanical/Switches/Toggle-Switches/_/N-5g2jZ1yzvvqx?P=1z0z28fZ1z0z2o3&Ns=Pricing|0
DPDT switches:
https://www.mouser.com/Electromechanical/Switches/Toggle-Switches/_/N-5g2jZ1yzvvqx?P=1z0z2xkZ1z0z2qcZ1z0z810Z1z0z80lZ1yy48toZ1yyg5u9Z1z0jl5uZ1z0zlgaZ1z0sf9tZ1z0zlgkZ1yzs6ii&Ns=Pricing%7c0
A center off switch could be mounted so that the on positions are left and right
instead of up and down.

| Subject: | Re: LED Noise Filter |
Thought I should update the list with our results.
I manufactured a couple filters as per the diagram above and Bob's
suggested components. Took our noisiest light to my friends avionics shop
and powered it without the filter while looking for noise on the power
lines. We saw very very little noise on the power lines so we decided to
have a look at the frequency noise and from 5 feet away the radio noise was
very noticeable. Wish I had recorded the actual numbers. In any case the
noise from one light was enough to break the squelch on a radio, and enough
to noticeable hear even while listening to a strong radio signal.
So while loosing hope that the filters would cure the problem but without
being able to come up with a better plan, we installed them in the aircraft
and gave them a try. Total success. It is now barely possible to hear any
noise when operating the lights in the hangar, once the engine is started
no noise is noticeable.
Thank you all for your help.

It is true that we've chronicled a hand full
of failures in the S700 series switches here
on the List over the years . . . but few
of the total were precipitated by loosening
of the rivets.
Here is one failure analysis conducted
on a Lister's experience:
https://tinyurl.com/2a2qqp
This style of switch by Carling was used on
tens of thousands of TC aircraft for a couple
decades. Aircraft represent a tiny fraction of
total sales for the product line.
The failure rate, while not zero, has been
exceedingly small and driven mostly by
the latest generation of strobe lights that
feature constant power high voltage supplies . . .
they draw substantially more current during
pre-flight ops with the engine not running.
I think a search of the List archives will
turn up some threads on other failures, most
having root cause OTHER than loose rivets.
Bottom line is that while there is good
cause to be skeptical of the rivets-thru-
plastic joints, experience has demonstrated
the mechanical stability of Carling's choice
of plastic.

John,
Those are Schottky diodes (which sow up as 'obsolete' on the Digikey web
page).
Lots of Shottky dual diodes, and singles as well, on ebay & Amazon.

How abouit DSTF3060CR Schottky, 2 diodes in one TO-220-2 package, available at
Mouser? Save on shipping cost by ordering Schottky diodes and current limiters
from same source.
