Wiring a 3 way switch with multiple lights. For example this allows lighting in a hallway stairwell or other large rooms to be controlled from multiple locations.
3 Way Multi Switch Installation 4 Wire Switches Amp Dimmers
Multi light switch wiring. 3 way switch diagrams for multiple light 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. You can do this light switch wiring in one of two ways. In this circuit two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional light. It is true that there are several wiring configurations for wiring 3 way light switches and all of the wiring configurations will depend on where the incoming circuit power is located. Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1.
Multiple light switch wiring. Another nm cable connects the first outlet box to the next box es and so on until you reach the end of the chain. This diagram illustrates wiring for one switch to control 2 or more lights. The most common is to daisy chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a home run configuration. The source is at sw1 and 2 wire cable runs from there to the fixtures.
Multiple light wiring diagram. With conventional light switch wiring using nm cable a nm cable supplies line voltage from the electrical panel to a light switch outlet box. Make sure replacement 3 way light switches have the same amperage and voltage rating as the original three way light switch and is the switch is fully compatible with the electrical circuit the light fixture and the type of light bulbs being used. While a normal light switch needs to be only a single pole single throw switch multiway switching requires the use of switches that have one or more additional contacts and two or more wires must be run between the swi. In building wiring multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.
