Switching receptacle connector

A switching receptacle connector for mating with a plug having a plug terminal, comprising:

• an insulative housing defining a mating opening and a plurality of receiving grooves in communication with the mating opening;
• and
• a plurality of substantially same pairs of first and second contacts, each pair of first and second contacts being received in corresponding receiving grooves of the housing, the first contact of each pair forming a first retaining section secured in the housing, the second contact of the same pair forming a second retaining section secured in the housing and a mating section for electrically connecting with the plug terminal of the plug to establish a desired relationship of electrical connection between the mating section of the second contact and the first contact;
• wherein, before the plug terminal of the plug is inserted into the mating opening of the housing to electrically engage with the mating sections of the second contacts, the first and second contacts of each pair are electrically connected;
• wherein each of the second contact forms a contacting section at a free distal end of the mating section for electrically contacting the respective first contact;
• wherein the first contact of each pair forms an abutting section extending from the first soldering section for electrically contacting the contacting section of the respective second contact;
• wherein an insulator is formed at a junction between the abutting section and the soldering section of each first contact for separating the first contact from the plug terminal of the plug when the plug terminal is inserted into the mating opening of the housing to electrically engage and to deflect the mating section of the respective second contact;
• wherein each first contact forms an abutting section together with the mating section of the respective second contact to define a passage in conformity to the configuration of the plug terminal of the plug;
• wherein the housing defines a pair of engaging slots proximate each receiving groove for engaging the retaining sections of the first and second contacts of each pair;
• wherein each of the first and second contacts forms a soldering section;
• wherein the soldering section of each of the first and second contacts is adapted to be surface mounted to a circuit board.
