With conventional light switch wiring using NM cable, a NM cable supplies line voltage from the electrical panel to a light switch outlet box. Another NM cable connects the first outlet box to the next box (es) and so on until you reach the end of the chain. Before 2011, the "end of the chain" switch was commonly wired using a 3- way switch wiring option. Diagrams shown on this page are.. This article and detailed wiring diagram explains how to run two lights from one switch.
Multiple Light Wiring Diagram This diagram illustrates wiring for one switch to control 2 or more lights. The source is at SW1 and 2-wire cable runs from there to the fixtures. 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. This is the simplest arrangement for more than one light on a single switch.. Wiring multiple lights to a single light switch is similar to the basic light switch configuration with the additional light bulbs attached to the first one as shown in the diagram.
