Part 1.
Have 2 red wires and one brown going into my ceiling pull chord UK light switch in bathroom. (see image) Will test when get my meter (assume I need pull out joint wired wires first to seperate and run an earth into bathroom first before I try test .) but can anyone suggest what wires each is likely to be and why there are two in L1.
PART 2.
Reason I ask is that I want to replace my fan with a constant live zvara,(Bluetooth controlled) but currently the configuration shown leads then to an isolator switch (there must be a junction or loop box I assume in between buried In wall I'm yet to see) but the isolator switch then has the expected 3 wires going in and out, as shown black Brown grey.
I tested these previously for another purpose and odd wiring it seems, but but the GREY is the PL The black the Neutral and the brown the SL.
So with this in mind I have fed the Grey PL into Live and and black into N and capped the brown SL into the zvara fan. BUT.. when the light is switched off its killing the current to the fan dead. Thus switching off the PL
(to note I did have the brown and black plugged into the live on the fan and grey into neutral and... All scenarios turned the fan on and off when the light switch was turned off!?)
Can anyone suggest the configuration that's causing the live feed to lose power With the light switch off... As when off both grey black and brown all have zero V.. Light on grey has 230v.
How do I ensure the live is constant and no longer impacted by the switch.
