Convert 3-Way Circuit to 2-Way Circuit

Posted by davidpj (My Page) on

in our 5 year old house I'm removing a 3-way switch and converting it to a 2-way circuit to work with a standard single pole switch. However, the colors of the wires I found at the 2 switches have thrown me off. I don't have good access to the wiring at the light fixture itself so I can't verify those wire colors.

The 3-way switch that I'm removing has these wires:

Black Screw: White wire
Silver/Brass Screw above the black screw: Red wire
Silver/Brass Screw across from black screw: Black wire
Ground

The 3-wire switch I'm replacing:

Black Screw: Very Dark Gray wire
Silver/Brass Screw above the black screw: Black wire
Silver/Brass Screw across from black screw: Red wire
Ground

Could you please suggest the wiring changes needed or how to determine the connections? Thanks.

At the switch you are removing connect the white and black together, cap off the red.

At the switch you are retaining, connect the black wire and the very dark gray wire to the new switch, cap off the red wire.

ronnatalie,

I did as you suggested and the circuit now works as a standard 2-way circuit. Thanks again for your help.

I also have the same question, except my switch is wired slightly different and I also have an extra step. Could you please advise on the following:

The 3-way switch that I'm removing has these wires:

Black Screw: Black wire (from shared cable to other switch)
Silver/Brass Screw above the black screw: White wire (from shared cable to other switch)
Silver/Brass Screw across from black screw: Red wire (from shared cable to other switch)
Ground

The 3-way switch I'm keeping has these wires. This is where the power source comes in:

Black Screw(Common): Black wire (from power source)
Silver/Brass Screw above the black screw: White wire (from shared cable to other switch)
Silver/Brass Screw across from black screw: Red wire (from shared cable from other switch)
Ground
**Note: The White wire from power source is twisted off in a group of other white wires from other switches in the gangbox.


Additional task: I have a separate 2way light switch next to the 3way switch(mentioned above) in the gangbox. I would like to wire this 2way switch into the 3way switch (or maybe vice versa). I want all lights in the room from both switches(2way and 3way) to function off a single switch, so perhaps wiring the 3way switch into the 2way is easier once the unneeded 3way switch is dealt with appropriately?

Thank you for your help!
