The type F plug, defined in CEE 7/4 and commonly called a "Schuko plug", is like type E except that it has two earthing clips on the sides of the plug instead of a female earth contact. The Schuko connection system is symmetrical and unpolarised, allowing live and neutral to be reversed. The socket also accepts Europlugs and CEE 7/17 plugs. It supplies up to 16 Amperes. It is used in Germany, Iceland, Latvia, Finland, Chile, the Netherlands, Norway, Portugal, Spain and Sweden.

This two-prong plug is popularly known as the Europlug. The plug is non-earthed and has two round 4 mm (0.16 in) pins, which usually converge slightly towards their free ends. It can be inserted into any socket that accepts 4 mm round contacts spaced 19 mm (0.75 in) apart. It is described in CEE 7/16[12] and is also defined in Italian standard CEI 23-5 and Russian standard GOST 7396."
