are earthed plugs that fit in CEE 7/3 (Schuko) as well as CEE 7/5
(French*)
sockets, because plugs have both earth clips and a contact for sockets
that have an earth pin. CEE 7/7 plugs - rewirable or integrated with a cord - are often made by companies that sell products in many European countries, irrespective the local socket standard. It is also a profitable strategy for production of special types that have a smaller market share than sales of plugs for domestic use. CEE 7/17 plugs, the not earthed version of CEE 7/7, are shown on a separate page. * CEE 7/5 sockets and 7/6 plugs are often designated as French type, but it is debatable whether 'French' is correct; see page about origin of earth pin sockets. |
