Abstract

In a theft security system fixed wall socket (6) includes a switch (10) closed by insertion therein of a plug. The switch is coupled one side with the phase connection of the socket, and on the other side to a switched wire (5) which feeds a switch relay (11). The other side of the realy is connected to the zero voltage wire (3) of the network. By the opening of the switch (10), resulting from removing the plug, or by drop-out of the network voltage, and alarm is sounded. In the connection with the alarm relay (11) there is pef. coupled a current limiter (12). For securing several sockets, the switches are series-coupled and the first is connected to the phase connection.
