This page contains wiring diagrams for household light switches and includes: a switch loop, single-pole switches, light dimmer, and a few choices for wiring a outlet switch combo device. Also included are wiring arrangements for multiple light fixtures controlled by one switch, two switches in one box, and a split receptacle controlled by two switches, plus more. When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used. This circuit is wired with a 2-wire cable running from the light to the switch location.

One black wire comes from the power source the electrical panel and the other goes to one or more light fixtures. When the switch is on, electricity flows through it from the inbound wire to the outbound wire. When you turn the switch off, it interrupts the flow of electricity. The wiring diagrams on this page show how to wire for a light switch. Always turn off the power to the circuit before working on wiring. Non-metallic cable used for wiring consists of one black wire, one white wire, and one bare or green grounding wire. The right way to wire a standard single-pole light switch depends on where the switch is located relative to the light. The diagrams below show the various options.
