* Compatible with ungrounded plugs.
† Deep-wall socket prevents human contact with pins.
‡ CEE 7/7 specifies a grounded hybrid plug that will fit into both the CEE 7/4 and CEE 7/5 sockets. CEE 7/17 specifies an ungrounded hybrid plug that will fit into both the CEE 7/4 and CEE 7/5 sockets.
1 Type letters are from a US Department of Commerce report that sees widespread but not universal use to differentiate plug and socket types based on rough mechanical compatibility. Most common household plugs have an associated letter.
2 There are some CEE 7/17 plugs with special shape which are polarised when used with CEE 7/5 sockets (mechanically only).
3 Plug can only be inserted one way with French CEE 7/5, but lack of wiring convention means that the system is not polarized.
4 Newer sockets can accept ungrounded Europlugs.

Famous quotes containing the words comparison of, comparison and/or sockets:

    “But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.”
    —Ralph Waldo Emerson (1803–1882)

    “The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
    —Virginia Woolf (1882–1941)

    “And in their blazing solitude
    The stars sang in their sockets through the night:
    “Blow bright, blow bright
    The coal of this unquickened world.””
    —Philip Larkin (1922–1986)
