Don, if I move the body of the plug laterally the tip of the plug in contact with the spring contact and switch moves laterally inside the jack itself with the ferrule at the opening of the jack acting as a fulcrum. So it's hard to understand why you think that cannot cause the failure.

That failure has nothing to do with lateral forces on the key jack, but is a failure that is related more to the number of times the headphone jack has been inserted and removed. If the lever is not operated, it is not likely to fail. 73, Don W3FPR On 11/23/2015 1:06 PM, Ron D'Eau Claire wrote: > The problem seems to be the leverage the plug provides to allow the plug to > move inside the jack and damage the switch if the phones cord is tugged. > > My K2 has the original jack after many hours of use, but as it happens I > have a right-angle plug so there is no long lever to apply force on the > internal components in the jack if I tug on the cord accidentally. > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
