A system for establishing an electrical interconnection for a helmet-mounted device comprising: a first interconnect mechanism mounted to one of a helmet and the helmet-mounted device, the first interconnect mechanism comprising: a first frame rotatably coupled around an axis to the one of the helmet and the helmet-mounted device to which the first interconnected mechanism is mounted, the first frame defining an opening in an interior thereof; a biasing member coupled to the first frame, the biasing member configured to bias the first frame in a predetermined rotational direction around the axis; a plurality of first electrical contacts positioned within the opening in the first frame; and a first projection extending from the first frame; and a second interconnect mechanism mounted to the other one of the helmet and the helmet-mounted device, the second interconnect mechanism comprising: a second frame fixedly coupled to the other one of the helmet and the helmet-mounted device, the second frame defining an opening in an interior thereof; a plurality of second electrical contacts positioned within the opening in the second frame; and a second projection extending from the second frame and positioned to contact the first projection, wherein as the first interconnect mechanism is moved toward the second interconnect mechanism, a contact between the first projection and the second projection causes rotation of the first frame in a direction opposite the predetermined rotational direction characterized in that the first frame comprises a substantially U-shaped frame, with the opening in the first frame defined between opposed arms of the U-shaped frame, and the first projection projects radially inwardly from one of the opposed arms of the U-shaped frame. a first interconnect mechanism mounted to one of a helmet and the helmet-mounted device, the first interconnect mechanism comprising: a first frame rotatably coupled around an axis to the one of the helmet and the helmet-mounted device to which the first interconnected mechanism is mounted, the first frame defining an opening in an interior thereof; a biasing member coupled to the first frame, the biasing member configured to bias the first frame in a predetermined rotational direction around the axis; a plurality of first electrical contacts positioned within the opening in the first frame; and a first projection extending from the first frame; and a first frame rotatably coupled around an axis to the one of the helmet and the helmet-mounted device to which the first interconnected mechanism is mounted, the first frame defining an opening in an interior thereof; a biasing member coupled to the first frame, the biasing member configured to bias the first frame in a predetermined rotational direction around the axis; a plurality of first electrical contacts positioned within the opening in the first frame; and a first projection extending from the first frame; and a second interconnect mechanism mounted to the other one of the helmet and the helmet-mounted device, the second interconnect mechanism comprising: a second frame fixedly coupled to the other one of the helmet and the helmet-mounted device, the second frame defining an opening in an interior thereof; a plurality of second electrical contacts positioned within the opening in the second frame; and a second frame fixedly coupled to the other one of the helmet and the helmet-mounted device, the second frame defining an opening in an interior thereof; a plurality of second electrical contacts positioned within the opening in the second frame; and a second projection extending from the second frame and positioned to contact the first projection, wherein as the first interconnect mechanism is moved toward the second interconnect mechanism, a contact between the first projection and the second projection causes rotation of the first frame in a direction opposite the predetermined rotational direction characterized in that the first frame comprises a substantially U-shaped frame, with the opening in the first frame defined between opposed arms of the U-shaped frame, and the first projection projects radially inwardly from one of the opposed arms of the U-shaped frame.
