Comment(by werner):

 Electromechanical :-) And the problem is that the connection is always
 open, though the switch should connect when there is no plug.

 Things I could think of:

 - a foreign object stuck between the contacts (seems unlikely, since the
   device is new and the contacts normally touch, i.e., things can only
   creep in while the plug is inserted)

   How to fix it: insert a jack and blow compressed air into all openings,
   in the hope to dislodge the object.

 - contacts oxydated or contaminated with something acting as an insulator.
   Again, seems unlikely.

   How to fix it: as above, but use contact cleaner.

 - some fault in the plastic, causing a protrusion that blocks the contact

   How to fix it: dunno. X-ray it, then apply a strong laser pulse to
   evaporate the offending plastic ? :-)

 - one of the metal parts is not at its correct position and is thus
   by the plastic

   How to fix it: try to bend it into its correct position by applying
   pressure with a suitable object, e.g., tweezers or a small screwdriver
   inserted into the jack's hole.

 Or it could be something else. Since most of this involves the application
 of force without really knowing what or where the problem is, I would
 discourage such attempts, unless you consider the device expendable.
