Wiring a 4 Way Switch with Light at the End

Warnings Check you local wiring rules, as your local wiring system may use a different color combination. These stranded wires are spliced to the cable wires from the house circuit. If you have a multimeter, use the continuity setting. If the connections are made with clamps instead of screws, tug firmly on the wires to be sure they are all still tight.

Two way switching (power feed via switch)

The power is routed first through the light ceiling box and then flows to the switches. Test the other posts to see which one has continuity and which does not. Never mix wire sizes or materials copper and aluminum. Run gauge electrical cable between each switch and the light it controls.

  1. Select the proper cable type.
  2. The white wire is marked black at each end to mark it as hot.
  3. Connect the traveler terminal between all the switches.
  4. It is not, however, authorized for use in all installations, such as being embedded in concrete or where exposed to the risk of physical damage.

Repeat this wire connection process at each switch connection. If you find travelers using white wires, use colored tape to mark each one in each junction box or device box where you find it, so that it will not be incorrectly viewed as a neutral wire. Such markings are not needed with this type of switch, as they are with a single-pole switch. Current electrical codes require any switch box without built-in clamps to have the wires secured within eight inches of the box. Mark both ends of this wire by wrapping it with black electrical tape to alert others working on the circuit later that it is no longer neutral.

Understanding Three-Way Wall Switches
  • Double-check that all connections are proper before carefully packing the wiring and switches back into each switch box.
  • Connect all traveler terminals between the switches and the circuit will work as planned.
  • This is intended to reduce the risk of accidentally shorting things to the terminals.

4 Way Switch Wiring with Light First

These screws, often gold, will be on opposite sides of the switch. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.

For hallways and tightening the same install appropriate electrical boxes for the correct circuit guides. If the switch box is metal, dating a it also must be pigtailed to the grounding wires. Some boxes have clamps to hold onto the wires.

The size of all the wires in any circuit must be the same size. For safety, always install a three-way switch that has a grounding screw. Complete the connection by screwing a properly sized wire nut onto the joint tightly.

There is shown separately. Option Two Three way switch with the power going through the light. Ground connection diagram is actually made up. End-of-Run Lights Controlled by Two Three-Way Switches These end-of-run lights are controlled by two three-way switches with a two-wire cable power source coming through the first three-way switch.

Pull one end of each cable through the back of one of the light fixture electrical boxes. When obtaining power from a nearby electrical outlet or another circuit device, the new wiring must be the same size as those that supply the outlet. The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box.

Lightly tug on each wire to make sure they are both tightly connected. Pick the scenario you through wiring diagram.

Attach the black power cable from the wall to the general screw black in the three-way light switch. If you've mounted the switches in the same electrical box, you can omit this step. Is it possible to wire the four way switch to work like a single pole? The white neutral wire is not connected to it it is typically just wire-nutted in the box. There are three screw terminals on the body of the switch, in addition to the green grounding screw.

Electrical Made Easy

To ensure your safety, make sure you test the wires prior to attaching them to your switch with a voltage tester. Two grounding wires, plus one pigtail, tied off by a wire nut. They are wired so that operation of either switch will control the light.

Also, always turn the main power off before installing a switch! Twist the other end together with the ends of the three bare wires in the box. Or, as shown here, they can be wired so that the cables run through both three-way switches, then to the light fixture. The white wire is marked with black at each splice to identify it as hot.
