<p>A fused miniature light string set having a plurality of sockets receiving incandescent lamps, a plug at one end of string supplying power to the lamps and a receptacle at the other end for connecting another light string set to permit tandem stringing of sets. At least some of the sockets are adapted to receive shunt-type incandescent lamps having a shunt across the filament for permitting continued current flow if the filament burns out. All of the sockets are electrically connected in a series circuit by relatively fine gauge wire, other conductors being of a larger gauge. One end socket of this series has a terminal connected by one of the larger gauge wires to a plug terminal and by another such wire to a receptacle terminal. The other end socket similarly has one such wire connected to the other plug terminal and another such wire to the other receptacle terminal. The set is fused, there being a fuse associated with each end socket, either an in-line fuse holder or by fuse lamps in the end sockets, which are configured differently from the other sockets. The lamps are mounted in lamp holders of two different configurations, one receivable only by the end sockets and the other receivable only by the remaining sockets.</p> |
