1 Besides standard Italian plugs and socket the BTicino Magic series offers also "Presa per spine irreversibili", which means socket for polarized plugs (see no. 3). This is an uncommon type of socket, which is only used in cases in which changing line and neutral is not tolerated (for example specialized hospital or laboratory equipment). Occasionally, polarized plugs are also used for local networks with a different voltage (<230V) and/or direct current.
The socket is closed by a safety lid (bearing the word ‘’Magic’’ on it) which can be opened only with an even pressure on its surface by an appropriate plug. The plug is energized only when it is inserted fully into the socket. This also applies to socket no. 2.
2 Polarized BTicino 16A socket. The enlargement shows a guide (yellow triangle) and notch (orange triangle) which prevent the use of Magic type 16A plugs in a 10A socket (no. 1), but 10A plugs (nos. 3 and 4) can be inserted in a 16A socket.   {WaO}
