Light Switch Wiring Diagram 2 Wires. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.
The source is at sw1 and 2 wire cable runs from there to the fixtures. The red wire connects one set of brass terminals on the two switches and the black wire connects the other set. Here is our selection of two way switch circuit diagrams.
The red wire connects one set of brass terminals on the two switches and the black wire connects the other set.

This diagram illustrates wiring for one switch to control 2 or more lights. The bottom terminal on one of the switches is used for the black wire coming from the power source and on the other switch it connects to the black wire going to the light. This 3 way switch wiring diagram shows how to wire the switches and the light when the power is coming to the light switch.
