Ok, this will require to review the links but any help would be great. Is the advice on this page incorrect??

I have implemented a 4way switch as explained from the link below. It then advises that I can take onward power from the switch. So, I pigtailed a wire from the black and then the white to the 3 way switch (link also below)

When the 3 way switch is on, everything is fine. I can turn the power on and off with the 4 way, but when the 3 way switch is off I kill power to the 4way. It won’t work??

I have analyzed all of the wire but not finding any mistakes?

Power Source at 2nd Switch and Fixture Feed at 3rd Switch

Power source at 1 switch and fixture feed from same switch

Thanks ahead if you take the time to look at the link and help.

One of the most common mistakes is that the wrong wire ends up on the common screw of the 3 way switch. Now the location of the common screw on your 3 way switch may be different than the location in the diagram. the common screw is the odd color screw that is distinctly dfferent than the other 2, possibily darker than theother 2. So check the wired labelled to be connected to the common screw and be certain that is indeed on the common screw.

You may have a second problem. While Don is correct that proper wire must be on the common screw of a three way switch [black or brass being odd color] {other two screws are traveler screws and will be of matching color} you may also have a problem with connections on the 4 way switch.

The four way switch you will find will have two screws of matching color and then two more screws of different matching color. You will have two cables with two wires in each cable. The two wires coming from the same cable must go to matching color screws on the four way switch. Also the second cable will have two more conductors in that second cable the two conductors from that second cable must be connected to the second color matching set of screws on that four way switch.

The problem you discribe can be caused by what either Don discribed or what was discribed in this reply or both may switches may be wired to the wrong screws.

Hope this helps

First I would suggest you start your own thread in the future as this is not related to the original post. To accomplish what you want consider using a contactor to turn on the lights and then a 3way switch to turn on the contactor. Get a contactor with a 120 volt coil.
