Review on BesMelody 2 Pack Power Button Switch by Marco Roberson

I received these cords to use on a lamp I am making. I wanted one with a built in switch. When I received them I found that they are not UL and the wires look very cheap and don't match the code. I've done a lot with changing cords and they don't have a "ribbed" cord that indicates a "cold" wire like any other cord I've seen. I would NOT recommend buying them. I should have studied the list better. No returns as the shipping costs are the same as the product price. They will go in the trash.
