ABSTRACT:
A universal power adapter has a choice of configurations for use in different countries and with different items of electronic equipment. A plug base for pivot connection with the adapter body has conducting pins for connection with an electrical socket and corresponding electrical terminals connected electrically to the pins. A rotational safety cover is provided to shield the electrical terminals and avoid unintentional contact. The cover has openings permitting access to the terminals when the cover is rotated. The body has a lug for engaging the cover to rotate the cover when the body is secured rotatably to the base. A power cord extends from the body to a mating socket and detachable adaptor tips. A voltage selector switch for selecting voltage has a semi light transmissive indicator disk with a light beneath the disk indicating the selected output voltage and operational status of the adapter.
