Type J vs. Type N
Comparing 2 standards across 7 specifications. 7 key differences identified.
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 N is used in two places -- Brazil and South Africa -- but they are genuinely different implementations, not one standard: Brazil's NBR 14136 uses two different pin-diameter variants and skips a shutter requirement that South Africa's SANS 164-2 (closer to the source IEC 60906-1 spec) includes.
