I am adding a receptacle for plugged lighting under cabinet in the laundry that I would like to be switched. I have 2-wire power with ground coming in to a 3-way light switch (#1). A 3-wire with ground goes to light fixture, then on to other 3-way light switch (#2). The receptacle does not need to also have constant power. How would I wire a switched receptacle from the #1 3-way light switch?
I guess I can’t put these images in comments, so posting an Answer here.
I have replaced a 3–way switch in a single box with a double 3-way switch. The upper 3-way switch controls the light and works at both ends. The lower switch has direct current and is wired to the newly added outlet. The outlet switches on/off with the lower 3-way switch but only when the 3-way light is powered on.
Can this lower switch be wired to control the outlet independent of the upper switch?
Following are photos of the double 3-way switch wiring and an edit of the earlier diagram describing the wiring from the double 3-way switch to the outlet.
