Need some help from wiring sifus biggrin.gif

I have a 4 gang switch controlling 4 LED lights (7.5W each) and want to change the switch to single gang, so that i can turn on all the lights at once.

Can anyone tell me if this is possible? and if yes, how would the wiring be like? Is it as simple as connecting all 4 of the light wires into the Load terminal of the switch?

Thanks in advance!

Yes. Make sure it can fit, and not fall halfway out, cause an arc, and a fire that burns down your house.

Thanks. Just want to ask if this is something that is normally done, or something that shouldn't be done? smile.gif (assuming i take all precautions of course to ensure the fit is good).

Reason why I am thinking of doing this is because I am looking into installing a Broadlink TC2 smart switch. Currently it doesn't work with my 7.5w LED lights due to low wattage (doesn't fully turn off, flickering etc). Would I be correct to think if i connect 4 of the lights into the same gang, it would then be a total wattage of 30W?

Right.. A regular switch will not have a Neutral..

TS needs to pull down a Neutral wire back into the switch box..

The Broadlink TC2 apparently was designed not to use a neutral line. I.e. one to one replacement with normal malaysian switch. Works with higher wattage bulbs perfectly but just not LED bulbs below 7.5W.

looks like you need to modify your wiring a bit?

Yes, adding the capacitor could be one option. But I am thinking if I just want to turn on all 4 lights at once, I can just connect all 4 to a single gang model ?

What I am trying to figure out is will the switch now see the total wattage as 7.5W x 4? i.e. Like just using a 30W LED bulb.

The max wattage of the TC2 single gang is about 300W and max 5A, so theoretically more than enough to handle the 4 lights.

Am i looking at this correctly?

yup, technically it's correct.
it should be more than 10W and it should work properly.

try it out and let us know!

Ok thanks. Now i need to figure out how to connect all four light wires safely into the 1 gang switch....
