==== 10&nbsp;A plugs and sockets (Type J) ====
SN 441011 defines a "Type 1x" series of 10&nbsp;A plugs and sockets. The type&nbsp;11 plug is unearthed, with two 4&nbsp;mm diameter round pins spaced 19&nbsp;mm apart. The type&nbsp;12 plug adds a central 4&nbsp;mm diameter round earth pin, offset by 5&nbsp;mm. The type&nbsp;12 socket has no recess, while the type&nbsp;13 socket is recessed. Both sockets will accept type&nbsp;11 and type&nbsp;12 plugs, and also the 2.5&nbsp;A [[Europlug]]. Earlier type&nbsp;11 and 12 plugs had live and neutral pins without sleeved pins, which present a [[Electric shock|shock]] hazard when partially inserted into non-recessed sockets. The IEC type&nbsp;J designation refers to SEV&nbsp;1011's type&nbsp;12 plugs and type&nbsp;13 sockets.<ref name=iec_typej>{{cite web |url=http://www.iec.ch/worldplugs/typeJ.htm |title=Plug Type J |publisher=International Electrotechnichal Commission IEC |type=official site |location=Geneva, Switzerland |access-date=26 May 2017 |quote=Type C plugs are perfectly compatible with Type&nbsp;J sockets. |archive-date=13 March 2018 |archive-url=https://web.archive.org/web/20180313031639/http://www.iec.ch/worldplugs/typeJ.htm |url-status=dead}}</ref>

The type&nbsp;15 socket is recessed, and has five openings (three round and two flat rectangular). It will accept plugs of types&nbsp;11, 12, 15 and the Europlug.
