The present invention relates generally to an electro-mechanic assembly comprising a snap connector. In order to provide a connection interface for an electronic device having a housing with at least one protruding stud which detachably fits within a socket region of the snap connector, the electro-mechanic assembly comprises a snap and at least one material layer being in at least one portion electrically conductive to electrically connect least one electrode with the snap. At least one surface of said snap is metallic and deposited with a non-oxidizing conductive material layer which faces and is in contact with a conductive portion of the material layer.
