This adapter plate makes it super easy to use the Sonoff TX Ultimate wall switch on a standard U.S. 1 gang, 2 gang or 3 gang electrical box. This will fit any of the TX Ultimate (120) wall switches. When installing the 2 gang adapter plate, remove your old switches and re-use the old screws to attach the plate to your electric box. Then use the screws that came with the TX Ultimate to attach the TX Ultimate to the adapter plate. When installing the three gang plate, just use the two screws included with the TX Ultimate to screw through the plate into your electric box. Very easy! Two gang means your electric box holds two light switches and three gang means it holds three light switches. Available in white or black.
