Gold Lamp Cord with Plug & In-line Switch is a convenient option when rewiring lamps. No need to reach up under lamp shade as easy-to-locate switch is positioned on lamp cord. Use with a keyless socket.
Standard insulated 18 gauge wire has 2 parallel copper wires. The positive/hot is smooth, neutral/negative - has ribs. U.L. Listed for table & floor lamps were cord is exposed. Stripped, copper-tipped ends simplify wrapping wire around socket screws. Molded-on plugs are polarized and permanently attached to lamp cord. SPT-2 rating has thicker plastic insulation, see below.
The SPT thickness-rating provides varying degrees of resistance to heat and abrasion. Higher SPT rating numbers provide more resistance to abrasion and more protection from electric shock.
This arrived with a broken switch. Paxton offered to send another, but I had gotten a replacement switch locally.
