The Filiba Safety Socket was invented by Dr. Yaakov Filiba and carries world-wide patent. It can be used in most of the countries in Europe, Asia and the Middle East. In addition, there is a North American version of the socket.
The Filiba Safety Socket ensures that the electrical contact occurs only after complete insertion of the plug into the socket and a 30 degree swivel of the plug.
The Filiba Safety Socket prevents electric shock or electrocution. It would not enable any electrical contact if a metal object were to be inserted into one of the holes in the socket, because the mechanism of the socket would not permit the plug to be swiveled without full insertion of the pins of the plug into the socket, and in such a situation there would be no electrical contact.
In the Filiba Safety Socket, swiveling the plug in order to enable the electrical contact and the flow of electricity cannot take place until the plug is completely inserted into the socket. Without full insertion no electricity will flow and there would be no dangerous over-heating.
The Filiba Safety Socket avoids situations common to standard sockets where the socket may be pulled out of the wall when the plug is withdrawn from the socket. Only when the plug is swiveled back can the plug be easily and smoothly extracted from the socket, thereby preventing the danger of tearing out the socket from the wall.
The Filiba Safety Socket doesn't need any special preparation or change in the standard building infrastructure. The size of the Filiba Safety Socket is identical to the size of standard sockets, and fits into the same holes in the wall.
