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. |

12 Unusual CEE 7/7 socket with an additional earth pin. Socket is in fact a combination of sockets 2a and 2b shown above. However neither CEE 7/4 (Schuko) plugs fit because of the earth pin, nor CEE 7/6 (earthed French-type plugs) because of the earth clips. Only earthed CEE 7/7 and not earthed CEE 7/17 and CEE 7/16 can be connected. These Turkish sockets are known as UPS sockets because they are powered by an Uninterrupted Power Supply. To limit unnecessary use of UPS, it is not possible to connect CEE 7/4 plugs, the standard type earthed plug in Turkey. Image 12 is based on photos taken by Atahan Acar who spotted the red sockets in a Turkish university library and also in a hospital emergency room. |
