I just upgraded the swtich for my diner table light.
This light is controlled by 2 switch, one in the hallway and one dimmer from the wall in the room itself.
When I took the switch out I noticed that the one in the hallway is a 3-way type (3 wires) but the dimmer has only 2 wires.
How can that be ???
I installed a new 3-way dimmer where the 3-way switch was and a new 2- way switch where the old dimmer was.
Of course, everything still works since I did not play with the wires setup.
Any info would help ...
