One customer said that he was looking for a two-button remote controlling two lamps with different voltages simultaneously. Working voltage of one lamp is AC220V, another is DC12V. Push button - ON, push another button - OFF.br br We recommend 2 receivers model of S1X-AC220 and S1X-DC12, with one remote C-2. Two receivers are connected to two lamps accordingly. The remote is supposed to control two receivers.br br Operation please see the video.
