(Click [here](https://docs.ifreeq.com/general-knowledge/electricity/plug-socket-and-voltage-by-country) for the full list of all countries that use type J) ![](/files/-MBpp0nt16hjQHlSyoDm) Switzerland has its own standard which is described in SEV 1011. This plug is similar to C, except that it has the addition of a grounding pin. Type J plugs have three 4 mm round pins, measuring 19 mm in length. The centres of the line and neutral prongs are spaced 19 mm apart and they have 10 mm long insulated sleeves. Older versions of this plug have unsleeved pins. ![](/files/-MBpp3oPLUtIDhl_MikY) Type J looks very much like the Brazilian type N standard, but it is incompatible with it since type J has the earth pin further away from the centre line than type N: the centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 5 mm. This connector system is rated for use in applications up to 10 amps. Above 10 A, equipment must be either wired permanently to the electrical supply system with appropriate branch circuit protection or connected to the mains with an appropriate high power industrial connector. A type C plug fits perfectly into a type J socket. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.ifreeq.com/general-knowledge/electricity/plug-and-socket-types-around-the-world/power-plug-and-outlet-type-j.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
