Wiring Two Separate Lights One Switch

The red wire connects one set of brass terminals on the two switches and the black wire connects the other set.

Wiring two separate lights one switch. Another black wire for light 2. The black wires going to the motion light fixtures need to join together but not on the switch instead splice the two wires after the switch. If there is only one black wire connected to the switch follow the instructions in step two. Here two switches are wired in the same box to control two separate lights.

With this wiring configuration you would end up with 3 black wires. Check all wires for current with your voltage tester. Basically the simplest way to have multiple lights on one switch is to run a power supply wire to the switch first. One black wire for the switch as the power source.

You can do this light switch wiring in one of two ways. 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. To wire this circuit in this manner you will need to run a 14 3 between the two light boxes. Adding an extra cable to the existing ceiling rose.

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. Wiring two switches for two lights. If there is more than one black wire connected to the switch follow the instructions in step three. How to wire two separate switches lights using the same power source.

One black wire for light 1. 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. It isn t unusual to wire two or more light and switch combinations from the same power source in fact it s common practice. This would be a two wire cable black white ground take the black wire and connect it to one screw on the switch and connect the ground wire to a screw inside the electrical switch box mounted to the wall.

One source is spliced to each switch with a pigtail to power the two lights. This will allow you to connect the first light as you described above and to run this additional light from the same switch by utilizing the red conductor in the 3 wire as the switched conductor and the black wire as the continuous hot wire. The source is at the switch box and a 2 wire cable is run to each light. To add a second light which is switched with the first one the switched line neutral and earth need to be extended to the second light.
