This adapter plate makes it super easy to use the Sonoff NSPanel on a standard U.S. 1 gang, 2 gang or 3 gang electrical box. 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 NSPanel to attach the NSPanel to the adapter plate. When installing the three gang plate, just use the two screws included with the NSPanel to screw threw 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. THESE ALSO WORK FOR THE TX ULTIMATE WALL SWITCH.
