I am trying to replace the old switches in my 3 way switch setup. The old switches are
I replaced switch 1 which had 2 travelers, 1 common/ load wire which was normal.
But while replacing the switch 2 , I noticed that there is only 1 traveller wire and 1 load wire. The old switch was connected to only one traveller and one neutral, it was not connected to the load wire. I was surprised how the previous setup worked well.
In the new switch I connected one traveller to the traveller screw, load to the load screw and the switch powers up but it does not function as 3 way switch, both the switches work as normal switches independently.
I am guessing the old switches had some support to handle this internally. Has anyone worked with these Jasco switches earlier? How can I enable the 3 way switch with only one traveller wire?
