PROBLEM TO BE SOLVED: To eliminate an extensive 3 terminal socket by a method wherein a terminal is formed at the ends of a pair of main lead wires which are connected to an attachment plug, and respective leading ends of a plurality of branch lead wires which are attached on the terminals are connected to 2 terminal sockets at both ends of a 2 terminal socket for electric lamp, which is serially connected. SOLUTION: Main lead wires 24, 25 are connected to terminals 26, 27 which are formed at the ends of a pair of the main lead wires 24, 25 connected to an attachment plug 1, and at the same time, branch lead wires 28, 29 and 30, 31 are connected. The leading ends of the plurality of branch lead wires 29, 29 are connected to 2 terminal sockets 32, 33, and in the meantime, the leading ends of the branch lead wires 30, 31 are connected to 2 terminal sockets 34, 35. Then, 2 terminal sockets 32 and 36, 2 terminal sockets 36 and 38, 2 terminal sockets 38 and 34, and 2 terminal sockets 33 and 35 are respectively connected with connection lead wires 37, 39, 40, 41, and a parallel circuit which is constituted of a serial circuit comprising a set of the 2 terminal sockets 32, 36, 38, 34 and a serial circuit comprising a set of the 2 terminal sockets 33, 35, is formed. |
