    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 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=484736#484736

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? Bob . . .

    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. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=484740#484740

    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. Bob . . .
