Im currently trying to upgrade two three-way light switches in the kitchen to some new smart three-way switches. The issue I have run into though is that there appears to be two common wires on one of the switches? The other switch has just one common but this one appears to have two. See picture below.
Picture shows the old switch with the wires already disconnected.
Any idea which one is which here? I believe the two wires on top are the traveler wires but not sure about the bottom two.
