I could infer from this discussion that 3.5 mm and 1/8 inch are two different types of connector but I find no evidence of that.
The terms are used interchangeably by manufacturers. Switchcraft, for instance, titles their products as 3.5 mm but goes on to say "all products are 1/8 inch." On their drawing you'll see the plug diameter given as 0.14 inch +/- 0.01. That's 3.56 mm +/- 0.25. They're also not cheap, but I recently bought some to try as I too have found this type of connector to be generally unreliable. The one that I went to the trouble of measuring showed poor sleeve contact. Maybe it's a corrosion problem. Lightly polishing the sleeve has helped with some of mine. Others remain incorrigible. I have not been able to find any industry standard for these connectors. 73, Carl WS7L K3 #486 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
