Sir Scottc12 . . . . .
I just now see that this info was left from the top post, as another part . . .
I was surprised by the way that outer connector case split, in just the way that it did. Thereby it was exposing the pic #1 view, that is showing the pressure contact that the inserted plugs outer barrel connector, presses down against (see the friction marks of repeated insertions ) and breaks switch contact with the upper switch leaf that is extending across the top, above it.
Since the central pin contact is still on the separate plastic shell and riveted to it . . . as per Photo #2 . . . . it must receive the inner hole of the barrel connector and make contact with it, afte the barrel connector plug is inserted.
PLUS, there must be only the very slightest clearance for that barrel connnectors plugs outer shell to just clear . . .without its touching . . . . the switch contact that is being located just just below it.
So all in all . . . . your connector needed . . . will be containing a pressure activated switch within it, that will be OPENING a power circuit when a plug is inserted within the connector.
OR being in its normally closed position and be closing a circuitry connection when no plug is inserted.
And then, the tricky situation of meeting the size requirements of the outer shell of the barrel connector along with the diameter of the central pin connection of the connector, along with the overall length of the plug that will be used within it.
I have seen both long and some times, shorty plugs.
