ABSTRACT:
A lampholder for miniature light sets, which may be of two-piece snap-together construction or a molded, one-piece unit, has a socket at one end to receive a push-in lamp unit and a wireway at the opposite end. The socket receives two identical push-in contact plates which are laterally reversible so that in one position they project by a respective insulation-severing element into one portion of the wireway to engage a first wire, and in a second position the severing element projects into a second portion of the wireway to engage a second wire. The wires are preferably contained in an insulated cord having cutouts at regular intervals which are located in the lampholders to be bridged via the contact plates and lamp units for a series connection. The lampholders at the ends of each series may have one of their contact plates reversed to engage non-interrupted wires in the cord to provide a serial-parallel arrangement. The cutouts may be formed at the location where the lampholders are applied to the cord or previously.
