Here is a graphical illustration of wire connections at the 4-way switch: 4-way switch wiring diagram (Single Light) The general wiring of the 4-way switch is explained well in the video below:

A 4-way switch must be wired between two 3-way switches as shown in the diagrams on this page. A 4-way switch has five terminals: one ground and 4 circuit terminals divided into two matching pairs called travelers.

This project sheet shows various ways 3-way and 4-way switches can be wired to control lights from two or more locations. The switches must create a complete circuit for current to flow and the bulb to light. Black or Red indicates a current carrying hot wire (120 volts ac). Bare or Green indicates a grounding wire at ground/earth potential.

Here is a PDF version of this wiring setup to give you a better view (schematics & wiring). Also, all PDF files with the above diagrams can be downloaded here . Now, let’s get your house as comfortable as possible!

Connect the green ground wire on the Accessory Switch to the bare copper or green ground wire in the wallbox (See 4-Important Wiring Information). Identify the color of the wires that were connected to the blue screw terminals in Sections A & B.Connect. Please read before installing.

2024年1月19日 · Here we'll show you how to wire a four-way switch. Four-way switches must be installed into the circuit in between two separate three-way switches. We brought power to the first three-way switch box, which is common, but other configurations exist. Before starting any electrical project, plan your circuitry and the best route for cables.

This 4 way switch diagram #1 shows the power source starting at the left 3-way switch. This 4 way switch diagram #2 shows the power source starting at the fixture. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut.
