Thanks for the suggestion of this topic, Rajish. Sorry for the late reply.
Let's consider the simple 3-way switch diagram (i/o meaning input/output of phase, on to point 1 in the example):
+---+
| 1o--
i/o---/ | 3wS
| 2o--
+---+
Now, let's connect TWO simple 3-way switches to a lamp in next diagram (one switch as "in" other switch as "out"):
+---+ +---+
| 1o----------------o1 | 3wS#2
in ---/ | 3wS#1 | \---out------(X)---> to Neutral or 2nd phase
| 2o----------------o2 | Lamp ON
+---+ +---+ both 3wS to
same point 1
Let's assume the dimmer 3-way switch diagram is as below, correct if I am wrong please, [DIM] is the dimmer in input only, bi-directional circuit not considered so output as not represented here:
+---+
| 1o--
in -[DIM]---/ | 3wSdim
| 2o--
+---+
If you want to use just one dimmer 3-way switch for just one lamp (incandescent/filament type for dimming), don't need to use both points (1 and 2), use just one point (point 1 in this example) and leave other point free/empty (point 2 here) like in the diagram below:
+---+
| 1o--out--------------------(X)---> to Neutral or 2nd phase
in -[DIM]---/ | 3wSdim Lamp ON
| 2o-- 3wSdim to
+---+ point 1
I think it will work. Regards.
