The Type J Electrical Plug is also known as the Swiss 3-Pin. It is similar to the Type C "Europlug," except it has an earth pin off to one side.
The Type J plug was developed by Switzerland as its standard, and is technically known as the SEV 1011 (Swiss 10 A/250 V). Swiss sockets can accept Type J or Type C plugs. Switzerland also has a two-pin plug, wtih the same pin shape, size, and spacing as the standard, but with a flattened, hexagonal form. This two-pin plug fits into both Swiss sockets and CEE 7/16 sockets.
