Type D vs. Type J
Comparing 2 standards across 5 specifications. 3 key differences identified.
Type D is the old British 5A standard (BS 546, 1934) -- three large round pins in a triangle. It predates and is completely incompatible with the UK's later Type G, and remains the primary domestic standard in India, Nepal, and Sri Lanka today.
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.
