Ladies and gentlemen, after having spent more than 2 hours with googling and without succes you are my last help.... I'm simply looking for a receptacle with an inner diameter of 1/8 inch (about 3,2mm) which must have a contact spring inside. The plug is just a cylindrical pin. I'm sure there must be something outside there, may be I'm just using the wrong search words. I would be pleased to get any help in this...
