Flip the switches and make sure the light turns on and off from all locations. Turn the power back on and test the switch to make sure it is working properly. Make sure to cap the wires with wire nuts. Connect the black wire to the black wire on the light fixture, and connect the white wire to the white wire on the light fixture. Connect the black and red wires to the two brass-colored terminals on one side of the switch, and connect the black and red wires from the other 14-3 wire to the two brass-colored terminals on the other side of the switch.Ĭonnect the light fixture to the 14-2 electrical wire that comes from one of the 3-way switches. Make sure to mark the white wire with black electrical tape to indicate that it is a hot wire.Ĭonnect the 4-way switch to the two 3-way switches with 14-3 electrical wire. Connect the black wire to the common terminal of each switch, and connect the red and white wires to the remaining terminals. I have 1 White, 1 Red, and 2 Blacks (we'll call them B1 & B2). When I pulled the older one out, the wires weren't clamped down very well and 3 of the 4 (yes, 4) wires popped out of place before I had a chance to look and see what was where. Use a voltage tester to make sure the power is off.Ĭonnect the two 3-way switches with 14-3 electrical wire. 2 I'm trying to replace an older style 3-way switch with a newer one. Klein Electrical Starter Tool Kit Wiring a 4-Way Switch: Step-by-Step Guideīefore you start wiring, turn off the power to the circuit by switching off the circuit breaker. Tools and Materials Neededīefore you start wiring a 4-way switch, you need to have the following tools and materials: 4 way switch wiring diagram multiple light 4 Way Light Switch, 3 Way Switch Wiring. It’s a convenient and practical solution for larger rooms, hallways, or staircases where you want to be able to control the lighting from multiple locations. When you flip the other 3-way switch, it sends a signal through the other traveler wire to the 4-way switch, which then directs the electricity in the opposite direction.Įssentially, a 4-way switch allows you to control a light or a group of lights from multiple locations without having to walk to the other end of the room to flip a switch. When you flip one of the 3-way switches, it sends a signal through one of the traveler wires to the 4-way switch, which then directs the electricity either to the other 3-way switch or to the light fixture. The 4-way switch acts as a kind of “traffic cop” for the circuit, directing the flow of electricity depending on the position of the other switches. The 3-way switches would be installed at either end of the circuit, and the 4-way switch would be installed in the middle. In order to control a light from three or more locations, you would need to use two 3-way switches and one 4-way switch. In this article, we will guide you through the process of wiring a 4-way switch.Īlso known as: 4 way switch, four way, 4 pole switch, four pole How it works With a 4-way switch, you can control a light or a group of lights from three or more locations.
