While a $16 switch and a $79 switch may be of equal quality, there certainly
can be a tremendous difference in the quality of similar-type switches.

I agree. However, a more expensive switch is not necessary more reliable than a cheaper one.... Very true. I called up one supplier who had one PTT for $16 and one for $79. I asked what the difference was and he said, not much. I said I'd pay for the more expensive one if it bought me something and he said it wouldn't. So I bought the $16 and used it a lot in our 152's as their yokes have no PTT. Held up pretty well. Gregg |

I asserted, "... there certainly can be a tremendous difference in the
quality of similar-type switches." And Gregg asked, "You mean in switches from Radio Shack?" I mean among all switches, not just those from Radio shack. Radio shack doesn't have any good switches. Besides, you can't pay $16 for a Radio Shack switch, can you? Let's see ... According to their web site, pushbutton switches (SPST momentary -- suitable for PTT) range from $2.79 to $3.49. A really good switch, the Newark 61F1210, is $19.57, according to their web site. Of course, we're talking about just the switch itself, not a complete PPT switch assembly. Jon |

I need to get a push to talk switch for the Cessna's I rent now. I have noticed that they are very expensive for what they are (a switch). Is it legal to build my own from Radio Shack type parts? If so, does someone have the specs? Note that the PTT circuit uses smaller than 1/4" (.250") diameter plugs and jacks. .206" comes to mind.
