Looking for a part, help welcome...

I'm looking for what Runoffgroove calls a "1/8 inch (3.5mm) closed-tip, open ring stereo jack."



Problem is, the terminology isn't very consistent, and waiting weeks for a delivery from China just to find out I got the wrong thing is super frustrating (not to mention that my searches on Ebay have yet to turn up anything that I recognize as being the correct part, any way).

It's to add a headphone jack to a mini-amp that will also shut the speaker off while plugged in (hence the closed-tip bit).

I think this might be it:

...but again, the terminology is different.  Also, $5 a pop is ludicrous.  Triply ludicrous if I don't even know that it's the right piece.

Anyone have a reasonable source for these?  Thanks in advance!!!

Edit:  

And it has to be the kind I can drill a hole, stick it in and screw the nut on to secure it.

Edit2:

I have no flippin idea what "open ring" means...

Might have found something that will work... Anyone who knows more about this?

I'm thinking what ROG is suggesting is similar (or exactly the same) as what IvIark suggests here:  http://tagboardeffects.blogspot.com/2012/04/noisy-cricket-mkii.html

And a switched headphone option.  An easier way of doing this would be to feed a switched headphone socket from the daughterboard, and the signal also going through the normally closed contact to the speaker output.  Then when a plug is in the headphone socket, the speaker will be diconnected automatically."

Either of the two stereo sockets on here will work.

The idea is that you need to break the circuit to disconnect the speaker when you insert the headphone jack.

The Tayda plastic case 1/4" jack sockets have these connections too, but you usually snip the tags off or leave them unused. You might want to use them for an active circuit on a guitar to avoid popping when you insert a "live" lead for example.

Well, I'll be damned.  Those DO have the little switching contacts.  Hot damn.  Thanks, Beaker.
