This bamboozled me at first since the cable coming out of it is 3 core: brown, blue and yellow/green. How do you open/close it??? The writing on the top is in Chinese.
Taking it apart and experimenting with a multi-meter revealed that:
Blue is neutral
Brown is live to make it close
Yellow/green is live to make it open, not earth.
I'll have to grit my teeth to wire up yellow/green to live but hey, in the end it is a copper conductor.
Apart from that it works, good value,
