An electrical safety plug connection in which the part of the power outlet accessible from the outside becomes separated from the source of power when the plug is pulled out. The power outlet has two chambers one above the other, the lower chamber being a self-contained chamber which contains the live contacts and which is separated by an insulating partition from a receiving chamber thereabove which receives the plug. Bridging contacts are arranged in the insulating partition, and the bridging contacts extend from the lower chamber into the receiving chamber. In the closed chamber there is a magnetic body which usually rests on the bottom of the chamber but is freely movable in the upward direction. This magnetic body has connecting elements which connect the contacts to the source of power and the bridging contacts when the magnetic body is in an elevated position, but do not connect them when it is in its lower position, and it is caused to move to its elevated position only when the plug has been inserted in the upper chamber by a magnet carried by the plug.

An electrical safety plug connection comprising: a plug which is adapted to be connected to a line that leads to an electricity consuming device, said plug having contacts and a magnet; and a power outlet, said power outlet comprising: a first chamber, said first chamber being closed and substantially inaccessible from the outside thereof; a second chamber positioned above said first chamber, said second chamber being open and being accessible to and adapted to receive said plug; contacts leading to a source of power, said contacts being located in said first chamber; an insulating partition separating said first chamber and said second chamber; bridging contacts carried by said insulating partition, said bridging contacts extending from said first chamber into said second chamber and being adapted to contact said contacts of said plug when said plug is inserted in said second chamber; vertically movable magnetic means positioned within said first chamber, said vertically movable magnetic means normally being at a first lower position in said first chamber and having contacts which are adapted to connect said contacts leading to the source of power to said bridging contacts when said vertically movable magnetic means is above said first lower position in said first chamber, said contacts further being adapted to disconnect said contacts leading to said source of power and said bridging contacts when said vertically movable magnetic means is at said first lower position in said first chamber; and said magnet of said plug being adapted, when said plug is inserted in said second chamber, to cause said vertically movable magnetic means to rise within said first chamber to a second higher position to make contact with said bridging contacts and thereby with said contacts of said plug.
