| The plugs and sockets shown below belong to the 'mystery section' of the museum. To solve these mysteries I like to make an appeal to visitors of the museum. Please contact me if you know anything about one of the objects. Find the museum address below. |
| Porcelain 15-20A, 250V socket.
The three slots are positioned in an equilateral shape, with 23 mm
sides (see far right image). Slots can accommodate pins with a diameter of 4.8
mm. Other characteristics
of the socket are a centrally positioned logo, see far right image, and type or
catalog number 5351. The socket does not resemble to any of the nowadays domestic or heavy duty types. The origin is unknown. It has been bought at a garage sale and should come from an old Belgian house. This may indicate that the socket represents an obsolete French type. |

| This
socket was found in a Dutch physics workshop, but
unfortunately without any documentation or corresponding plug. The indicated rate is 220-380V, 10A. It
roughly looks like an Australasian type I socket, but dimensions and
angles of the slots differ. Also the earth slot
differs. The SK mark on the underside of the socket may relate to the brand name. Furthermore it has the following two numbers: E53-SO55.86 and 48251. Nothing is known about the origin and use of this unknown socket. |

| Israeli plug* with
flat
blades for neutral and live - positioned in line - and a round earth pin,
rated at 16A, 250V. Its configuration is identical to North American 15A, 250V plugs (NEMA 6-15P), but brute force is needed to insert the Israeli plug into a US socket, because the flat blades are 0.9 mm thicker than US blades. * Plug has the Standards Institution of Israel certification mark. Brand name: NISKO. Further details about the use of this type of plug are missing. It is unknown whether it is still in use in Israel or elsewhere in the Middle East, and for which purpose ? |
