between the apertures, offset by . The plug has two round pins measuring , spaced apart and with an aperture for the socket's projecting earth pin. This standard is also used in Belgium, Poland, the Czech Republic, Slovakia and some other countries. Although the plug is polarised, CEE 7 does not define the placement of the live and neutral and there is no universally observed standard. CEE 7/2 and 7/4 plugs are not compatible with the CEE 7/5 socket because of the round earthing pin permanently mounted in the socket. CEE 7/7 plug (compatible with E and F) The CEE 7/7 plug fits in either French or Schuko sockets. The CEE 7/7 plug has earthing contacts to connect to either the CEE 7/3 socket or the CEE 7/5 socket. It is polarised when used with a French CEE 7/5 socket, but can be inserted two ways into a CEE 7/3 socket. The plug is rated at 16 A. Appliances are sold with non-rewireable CEE 7/7 plugs attached. This plug can be inserted into a Danish Type K socket, but the earth contact will not connect. CEE 7/16 plugs The CEE 7/16 unearthed plug is used for unearthed appliances. It has two round 4 by 19 mm (0.157 by 0.748 in) pins, rated at 2.5 A. There are two variants. CEE 7/16 Alternative I Alternative I is a round plug with cutouts to make it compatible with CEE 7/3 and CEE 7/5 sockets. (The similar-appearing CEE 7/17 has larger pins and a higher current rating.) This alternative is seldom used. CEE 7/16 Alternative II "Europlug" (Type C) Alternative II, popularly known as the Europlug, is a flat 2.5 A-rated plug defined by Cenelec standard EN 50075 and national equivalents. The Europlug is not rewirable and must be supplied with a flexible cord. It can be inserted in either direction, so line and neutral are connected arbitrarily. To improve contact with socket parts the Europlug has slightly flexible pins which converge toward their free ends. There is no socket defined to accept only the Europlug. Instead, the Europlug fits a range of sockets in common use in Europe. These sockets, including the CEE 7/1, CEE 7/3 (German/"Schuko"), CEE 7/5 (French). Most Israeli, Swiss, Danish and Italian sockets, were designed to accept pins of various diameters, mainly 4.8 mm, but also 4.0 mm and 4.5 mm, and are usually fed by final circuits
