Interesting... Here I was thinking they were the same.
My Laptop from Switzerland seems to plug into my wall socket (https://www.livecopper.co.za/collections/wall-sockets/products/veti-2-single-switched-rsa-socket-with-3-x-v-slim-sockets-charcoal) just fine... Bit of a tight fit but not a problem... Maybe the SA plugs don't fit into the Swiss sockets?
Type N sockets (new SA) is designed to take type N plugs and type C (europins). Swiss type J is designed to take type J plugs, and type C plugs were designed to fit into multiple European sockets, including type J. From what I had read type N and J were not meant to be compatible, it's interesting that it works for you.
