US Patent 7210939 Conductive buttonhole interconnect

A wearable garment incorporates a manual interconnect device, so that a user wearing the garment can operate the interconnect device by coupling a connector, which is in turn coupled to a power source or external electronic device. Through a releasable locking action by the user, the connector is electrically coupled to the interconnect device, which is coupled to a fabric circuit integrated in the garment, such that operation of a locking action activates related ancillary equipment such as power supplies or electronic devices.
