Side-by-Side Comparison Plug Types

Type I vs. Type J

Comparing 2 standards across 5 specifications. 5 key differences identified.

Comparing:
Type I
Type J

Type I, the Australian/New Zealand standard, uses two flat pins angled in a V-shape plus a flat earth pin. China and Argentina use dimensionally similar but genuinely incompatible variants -- Chinese plugs don't physically fit, and Argentine plugs fit but with reversed polarity.

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.
