Thanks to all who responded to the switch rating  question recently. On the strength of that, what is the consensus on using two  conductor wire for the ptt button on my right side stick? Should I go with the  cheapest 2 conductor 20 or 22 gauge wire or is something more high tech and  exotic called for here? Should I use a shielded 2 conductor cable? How about a  twisted pair? Let the education commence.

Hi Ed,



 I just did some searching on the net and failed to find anything useful about PTT wiring.  That means my comments are pure guesswork, and you should really ask the manufacturer of the device (radio or audio panel) maker to be sure you are not causing noise problems or other issues with your choices.



 I would guess the PTT function doesn't get involved in any audio signal quality issues and also doesn't take much current.  That means the only interesting issues left are how flexible the wire is and what sort of insulation it has.  Military folks don't allow vinyl wire insulation on airplanes because of the noxious funes generated when they are burned.  If you are worried about this issue then Tefzel insulated wires should be chosen.  If you use normal wire, selected stranded wire over solid because it is more flexible and less likely to break.



 Twisting the wires can't hurt, but probably won't make much electrical difference for this application.  I wouldn't use shielded wire for this function.
