4 way switch wiring with four switches. T2 from that switch is wired to t1 on the second 4way and t2 connects to the travelers on sw2.
How Three Way Light Switches Work
Four way switch schematic diagram. Start here for practical circuits with different arrangments of switches and lights including proper color codes. In the diagrams below the first switch 3 way common terminal connects to line voltage. This 4 way switch diagram 2 shows the power source starting at the fixture. Use this if you began repairing and replacing a 4 way switch circuit and ran into problems. A 3 way switch wiring diagram is a simple drawing showing how to connect the wires to each of the four screws on the 3 way switch. This 4 way switch diagram 1 shows the power source starting at the left 3 way switch.
My 4 way switches dont work. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut. My 3 way switches dont work. The two 4 ways are located between the two 3 ways and the traveler wires run from sw1 to t1 on the first 4 way. What is the black screw for on a 3 way switch diagram. The white wire becomes the energized switch leg as indicated by.
I have a few of the most common ways in wiring a 4 way switch to help you with your basic home wiring projects. Back to 3 way and 4 way light switches. The black screw on a 3 way switch diagram is for the continuous hot wire that comes from the circuit. A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch. A four switch configuration will have two 3 way switches one on each end and two 4 way switches in the middle. The first switch 3 way travelers brass color connect to one pair of the second switch 4 way travelers black or brass color.
A similar page for 3 way switch circuits. The diagram below is based on the video you watched above. Here two 4 way and two 3 way switches are used to control lights from four different locations.
