I use switches, but the stuff I work on is supposed to come back and get
reused. I don't use fuses.

As I stated before, we don’t use switches on flight hardware. Effectively, we
twist the wires together, but it’s done through a shorting plug on a
connector.

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.
