Type K
Type J →

Type J is Switzerland's own standard -- three round pins in a small hexagonal-bodied plug, in 10A and 16A variants. Its design directly influenced Brazil's and South Africa's later Type N standards, though reversed polarity during adaptation broke compatibility with its own descendants.

Type K →

Type K is Denmark's standard -- two round power pins plus a separate round earth pin mounted on the plug, offset from center. Used exclusively in Denmark, Greenland, and the Faroe Islands; EU accession has allowed Schuko (Type F) sockets in Danish homes since the early 1990s.
