Switching Answered

I have five existing wall lights that are hard wired to a single switch, running on 230v a/c
It's impossible to run alternate wiring as it's all embedded in the walls (which are three feet thick.)
 
I am going to convert each light to be dual-function, with (a) background candle-LEDs and (b) a couple of 5w LED spotlights
Already I have acquired 12v LED drivers and step-down transformers (12v to 5V) for the candle LEDs.
 
What I wanted to figure out was some electronincs to allow me to control them all by using the existing in-wall wires and perhaps replacing the wall switch with a push-button switch. What I had in mind was to be able to achieve different functions sequentially, possibly using an IC like a 4017.
However, I'm only a beginner at electronics, and I haven't been able to figure out a way to do it.
 
One sequencing that would be effective, commencing with an all-off situation, would be:
 
1st press = candle lights only on
 
2nd press = LED spotlights on (Candle bulbs remain on)
 
3rd press =  All off
 
Cycle then repeats.
 
If this proves to be impossible, I also considered the idea of short and long presses, which could trigger a timer for the long press to acomplish some switching
 
The power of 230v a/c will also be travelling down the same wires to give power to the 12v LED drivers in each lamp, so I'm actually talking about sequential presses on a 230v a/c circuit.

X10 is the simplest method I can see.

Thanks for all your inputs. I believe that I now have a solution............

I will leave the on/off 230v switch in place, and install a small wireless switch inside each lamp to turn the 2nd type of LEDs on/off, using a single common transmitter, which will be located adjacent to the 230v swittch.

Neopixels come to mind here as they only need a single wire for the protocol.
That is assuming you have a legal wiring for the lamps which includes the earth wire.

1. There is a big difference between being an electrician and an electrical engineer. Don't mess with 230vac mains house wiring unless you know what you are doing lest you get into a dangerous situation with yourself and burn down the house.

That said, research what commercial systems they have out there already to control lamp dimmers, lights, power outlets, etc by using the existing wiring all linked to some master control. They might communicate with the remote unit through wifi, bluetooth or inject a signal through the house wiring. From that, figure out what you want to do or figure out how your system should work. Good luck.

Hi CaitlinsDad:
I thank you for your comments, and will proceed with caution.
That said, I would certainly like to find out more about injecting a signal through the house wiring to accomplish my requirements.
Can anyone perhaps give me a link for such a commercial product ?

zwave, xbee, X10, and a whole slew of stuff on display at the home center HUE, etc. Good luck.
