A mounting socket includes an insulating socket body provided with a subscriber identification module card insertion recess and a memory card insertion recess. A metal housing coupled to an upper surface of the socket body defines the subscriber identification module card insertion recess. A lower metal plate coupled to a lower surface of the socket body defines the memory card insertion recess. An integrated sensing switch electrically connects the metal housing to the lower metal plate. The integrated sensing switch electrically connects or electrically disconnects the metal housing and the lower metal plate during insertion of a subscriber identification module card into the subscriber identification module card insertion recess.
