2 Ways Switch Wiring Diagram. Wiring diagram for a two way switch wiring diagram is a simplified customary pictorial representation of an electrical circuit. The source is at sw1 and 2 wire cable runs from there to the fixtures.
Two way switches have a com terminal as well as l1 and l2 terminals. As you can see in the schematic diagram of 2 way switch circuit below the common of both the switches are short circuited. Com on the first switch connects to com on the second switch l1 on the first switch connects to l1 on the second and l2 on the first switch connects to l2 on the second.
This can be confusing.
One gang two way switch fig a is the two way light switch mechanism fig b is the single gang switch face and fig c is the single gang two way light switch. Two way switch lighting circuit diagrams. One thing to remember is that the wiriing on light switches is. Coming to the actual wiring the following schematic shows the implementation of a two wire control two way switch.
