This is a combination of two devices. First part is a switch sensor (2-Fold) with 4 buttons. Second part is a relais actuator that additionally acts as a power supply for the sensor. The sensor (first part) will be plugged onto the relais actuator (second part). While the top most two buttons control the underlaying flush mounted device, the other buttons can be configured to control other lamps within the zigbee Light Link network. The Flush monted relais actuator is visible to the zigbee Light Link network as ON/OFF Light.
