How To Wire Multiple Lights On One Wall Switch

How to wire two separate switches lights using the same power source.

How to wire multiple lights on one wall switch.

Multiple light wiring diagram. 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 of the conducting wires is black and it s the hot one meaning it carries the electricity on its outward path from the power source to the load. Connect one wire to the first switch in the box and the second wire to the other switch and connect the black wire from each of the lights to the other terminal on its respective switch.

This diagram illustrates wiring for one switch to control 2 or more lights. 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. 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. Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1.

How to wire multiple 12v lights to a single switch. Every 120 volt circuit that powers lights in a typical home has two conducting wires and a ground. It isn t unusual to wire two or more light and switch combinations from the same power source in fact it s common practice. Wiring a 3 way switch with multiple 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. To wire this circuit in this manner you will need to run a 14 3 between the two light boxes. The switch must be between the fuse box and the lights. Before you can wire multiple light fixtures to a switch you have to know how to do just one.

Wiring multiple 12v lights to a 12v switch is just as simple as connecting the positives to positives and negatives to negatives and installing a spst switch between the fuse box and the string of lights. The white or neutral wires bypass the switch so the one coming from the power source and the one from the light get spliced and capped in the box. The source is at sw1 and 2 wire cable runs from there to the fixtures.
