Note: Though the CEE 7 standard was superseded by the IEC 60083 standard, many of the plugs and sockets have changed little in design—but perhaps more in material—since the last CEE 7 update was published. Despite the very earliest CEE 7 plugs and sockets having been more or less obsoleted, you will still find a few of them hiding out indoors in a few countries—specifically CEE 7/1 and 7/2, which were not grounded (earthed) plugs and sockets. However, the 7/3 German Type F socket that came soon after the 7/1 and 7/2 was the first grounded socket in the CEE 7 series.
