I'm trying to understand how a new CRL 3-way switch works, what is connected to what when the switch is in the 3 different positions. I found some diagrams that show the lugs labeled A0, A1, A2, A3, B0, B1, B2, B3, and in colors red and blue, in addition to some uncolored. I don't know how to interpret these diagrams. I want to know how the switch works electrically. I don't need a specific wiring diagram (yet anyway). If anybody can help me with this, or point me to a resource (with a full, simple explanation), I'd really appreciate it. Thanks.
