Wire Gauge for 2nd Comm Switch

[Piper J3]

I want to install a second comm PTT switch. Does anybody know Tefzel wire gauge for this application?

Thanks in advance...

PTT current draw is practically "nil". Pretty much any size wire will work.
I personally won't use anything smaller than 20 ga. just because of workability.

As Mel said but personally I use 22 ga for all signal wires, 22 is the smallest gauge I use.

I would go with 20 or 22 awg as well.

Thanks guys. 20 AWG wire is on order. I didn't realize that Tefzel is a little pricey...

I installed a comm 2 and used 22 gage wire for the PTT. works great!

Does the second PTT switch wire in parallel with Pilot's PTT or does it go back to the comm radio as a separate input? I think I've seen it shown both ways. I think it would be easier / cleaner just to wire in parallel with the existing switch.

I kept my wiring entirely independent of the original caomm. It has a dedicated PTT on the panel.
