The lower half of this switch can be divided into three blocks: one middle block for the LED light, and two switch blocks on the side. Each block is independent from other blocks. The power for the LED light should be connected to the middle block, which is represented by the same color as the LED color. There is no connection between LED light block and any of the NC or NO switch blocks. Two switch blocks are installed on the outer side. Additional blocks can be added to switch more pairs of wire. See the BK-SW15 of the additional block.  Whether the block is a NO or a NC block is printed on the side of its block. This can also be identified by looking at the bottom of the block. A green round dot indicates a NO block; a red round dot indicates a NC block.
