Maybe run another, parallel, experiment on top of your clothes dryer – twist
and untwist some wires a few times, every time you go in there… ;)

OMG, Chris Kobel is another twister. Well, it’s out there now thanks to
RickyLeaks. Like when I saw James D (one of the most technical savvy people I
know), twist the arming wires to his electronics and stick them in a two stage
rocket. I thought, OMG, my buddy is a bohemian.
So, perhaps shoe strings and belts would even been too complicated for you
guys. Yup, slip on shoes and elastic waist bands for you. 😊
So twisting wires or switches…Can you twist and untwist two wires 300 times
without a failure?
LOL

Full disclosure, I use switches on most of my dual deploy rockets. I had one
micro slide switch fail, thank goodness for independent, redundant electronics.
I’m twisting wires because I haven’t bothered (yet) to replace the failed
switch ☺

I hate the twisting wire technique. Yet, some people that I look up to
actually do this. It’s just so barbarian. And, then they stick the wires back
in a hole in the airframe. Freakn crazy dude.
I imagine someone twisting some wires on a Falcon 9 before launch. Hopefully
they would read the technical manual on how to do it correctly. If it was at
JPL, they would have the technician twisting the wires while two engineers
watch. LOL

More and more, this conversation is encouraging me to keep twisting my wires
together. Somebody mentioned it previously…is there a “right” way to do it, to
go along with all the wrongs ways I’ve tried?
(I do try to insulate the twisted wires and tie a piece of string on them so I
can fish them out of a breather hole to disconnect them after a flight…)

Sorry if there was a misunderstanding Ken. I don’t routinely have the
soldering iron dwell on the contacts that long. Just trying to figure out
potential failure modes for this switch. The objective is to provide
information to people that have already used these switches in projects, and
maybe others that will use them in the future. Verses, “hey, don’t use these
switches.”
For example: If someone is planning on using one of these switches, they could
have good information about how to install them and solder the contacts. Also,
and I think this is very important, they should be advised on how to check the
installed switch for problems before flying their project.
This helps not only for the case of using these switches, but for using other
electronics as well. Having detailed information on the device, and testing
before flying a project is always a good idea.
