1. I think rewiring at the DB end would be cleanest. If I’m not mistaken I only need to switch the Red Neutral with the Yellow Neutral (depending on which Live phase I use)
2. Or Xiaomi suddenly makes a three gang switch. This would solve all my problems
3. Or like you said, separate switch but since there is no more lobang, have to use external box. My boss sure won’t approve so ugly
How would you rewire if the wire is embedded in wall? YOu can rewire in the DB but you will have different phase color in another phase group. Will cause confusion for electrician in future.
I think any ganged switch would have 1 common Live input. So, would not solve the problem
Enlarge the hole for another wall switch wouldn't be hard I think. It will look as nice but will have a look of two separate switch
I think there is a way you solve the problem. I'm refering back to the original wiring that you provided:
As you can see from left to right:
1) Red wire to bulb
2) Red wire
L coupled for looping
3) Yellow Wire to bulb
4) Yellow wire
L coupled for looping
I use different color to denote different phases (orange more visible than yellow
)
So, you just chose to use the
Red or
Yellow phase. Then connect the Red lamp and Yellow lamp to the switch (L1 and L2 if not mistaken). Then just joint the looping wire (either Red or Yellow) using connector by themselves.
This should work. No need to rewire anything. This is what I meant (not sure if your switch is like this. I didn't have one
)
