Connecting two switches to operate a ceiling light.


Following situation. Two rooms each with own entry door and light switch at the door for overhead light. Concrete walls, laying new cables is not an option, also cost point to > expansive and to complex because of rest of structure. One dry-wall removed to make both rooms in to one. The in-ceiling (concrete deck that according to the architect can not be touched to run new cables in it, static reasons) light points are not aligned with each other.

As the room will be used as an office we want to put one surface mounted track on the ceiling. As the in-ceiling light points do not align at all with each other, we can not put in two feeds on one track. Two tracks would look silly. So one in-ceiling light points will need to be blinded of.

It would however be nice to be able to operate the light from both entry doors. Is there a remote solution of some kind one could put in? Any other ideas as to how to solve this?

Thanks.

Re: Connecting two switches to operate a ceiling light.


The only way to operate the light(s) from two switches is to tie them together and utilize 3 way switching at both points, meaning running new 3 wire cable between them. You state that is not an option, so I don't have a ready solution.

Look into Zigbee or Z-Wave wireless switches.

Yes, there are several wireless switches available. Some do not require any other support such as a hub or internet connection. Search Amazon or EBAY.

OK folks, I think we are a bit of the trail. I need a solution that is in the wall behind the switch not in the lamp. As i will use a rail, there is not space for receivers there.

Nothing is required at the fixture. The wireless switches replace the existing single pole switches you have. You are looking for a master and slave switch.

So there is an existing switch for the one ceiling box you are going to use? You then buy a wireless switch which contains one wired switch which goes in the existing switch location and the other wireless switch (included in the kit) can be mounted at the other desired location (no connection to wiring).

Look at X10 products. They came out as one of the 1st remote control systems long before WiFi and the internet in the 1980's.

They are now Insteon. Thatís what I used - their micro dimming modules. They are great because you can use custom switches. Also check out Lutron Casetta. Their Pico remotes are great. Either option will work.

Insteon - programmable switches do not have to wired together to operate a light (or appliance, etc.).

They communicate using RF over the existing household wiring and they solve problems of wiring through concrete, etc.
