This product is not only a cable, it's ideal to connect the LED strip light to the DC power adapter, and turn the light on/off by the inline switch button that comes with it in just one go! With their built-in plugs, these connectors will save you time and effort by eliminating cutting and soldering in any project to achieve an easy plug-and-play installation. The male plug can make a direct connection with the DC power adapter, and the female jack can connect light strips, dimmers, or other accessories.
