The Clipsal 5031NMS range of switches (CBus slave mechs) can be integrated with the CommandFusion SW16.
The 5031NMS range have 2 LEDs in each button (orange and blue) and can also combine to get a purple color. The LED functionality can be fully taken advantage of by the SW16.
You can learn more about the 5031NMS range here: http://www.clipsal.com/consumer/products/powerpoints_and_switches/technology_range/standard_range
One SW16 can drive 8 switches. To integrate the switches you will need to cut off the plug that comes on them, there is a specialised PCB available to make integration easier - contact us through our support page for more info.
