# Two 3-Way Switches and One 4-Way Switch Controlling two lights. How do I convert the 4-way to a single pole switch?

Here is the situation. At the top of the stairs I have two 3 way switches. (the left one controls the upstairs hall light and the office ceiling fan/light and the right one controls the ceiling stairs light) At the bottom of the stairs is the other 3 way switch that controls the upstairs ceiling stairs light.

There is a switch next to the bedroom that controls the Hall/Office ceiling light/fan just as the switch next to the bathroom controls the Hall/Office ceiling light/fan (I will call this light switch 2) What happens in this scenario is that, not matter what the Hall light is on, ALL THE TIME (very dumb), and we will call the switch next to the bathroom light switch 3.

What I want to do, is make the light switch 2, next to the bedroom to act as a single pole switch, independent of the others.

Here are some pictures.

We will call this light switch 1 because it holds two three way switches.

Here is the wiring for light switch one with the switch to the hall pulled out.

Here is light switch 2 next to bedroom (I want this to act as a single pole switch).

Here is the wiring for light switch 2.

Here is light switch 3 next to the bathroom.

Here is the wiring for light switch 3.

Here is the situation above the stairs and "hall", which technically a hall but kind of. Stair light is present and I removed the hall light.

• FYI, light switch 2 is a 4-way switch, not a 3-way. A "3-way" circuit has a 3-way switch at either end, with an unlimited number of 4-way switches in the middle. Each switch in the chain "swaps" the wire carrying the power (between black and red), effectively inverting the state of the device that's being switched. The input (or output) of the 3-way switches will be the screw labeled "COMMON"; the other two screws are for the carrier lines to the other switches in the chain. Commented Feb 10, 2021 at 19:25
• If the hall is the upper landing light for the stairs it is required to be controlled in the 2 locations upper and lower stairs. The most probable answer is no modifying the circuit will affect everything. I believe that’s why @ereisch provided the detail. I am curious if this was a legal configuration to start with I see 2 grounds that would point to multiple runs of NMB. So it may be possible to make changes but we would need a full schematic of the lights and where they are fed from (we can really only see the wiring to the switches) Commented Feb 10, 2021 at 23:12
• Is there a landing where light switch 2 is? Commented Feb 11, 2021 at 1:40
• @ChristopherLond -- can you get us closeups of the wiring inside the light boxes? Also, how open are you to running new cables? Commented Feb 12, 2021 at 0:39
