    Three wires and two switches should be dual control (i.e., remote control) switches, one with the live wire (i.e., the power line in and out of the two switches), and two control wires (the wire connected between the two switches).

    The light switch cannot lead out the wire to connect to the socket, because there is no neutral line.
