Back at the lights the source neutral is connected to the neutral terminal on L1 and spliced with the white wire running to the next fixture. With the power off and the device removed from the outlet box, check that all connections are still tight using a screwdriver. The black and red wires running between the switches serve as the travelers for the circuit. If you are trying to troubleshoot a 3-way switch operation, you will need to identify the function of each wire. At L2 this white wire connects directly to the neutral terminal on the light fixture. Here the neutral connects to the light F1 and is spliced through to light F2. To test a 4 way switch, connect one probe to one traveler terminal in a pair and the other probe to one traveler terminal in the other pair. Make a J-hook in the wire with a pair of pliers and wrap it around the black common screw on the light switch. Two wires attach to brass screw terminals, which are usually at the top of the switch, and an additional wire attaches to a dark-colored (not green) screw terminal, which is usually at the bottom of the switch. The first way of wiring uses a couple of Two-Way Light Switches with a 3-wire control. More lights can be added to this circuit by duplicating the wiring shown here for each additional fixture. Move one probe to the other terminal in its pair and test again for the same results. Step by step instructions on how to wire a switched outlet. Now, the actual wiring. They allow you the ability to turn the lights on or off from either location.

Connect the ground wire to the green screw. 3-way switches are useful for large rooms with multiple entrances but require a bit more wiring than a standard, single-pole switch. Saved by Russ Svatt. Two, 2-wire cables (C3 and C4) run between the fixtures, and a 3-wire cable (C2) runs from the second fixture (F2) to the second 3 way switch (SW2). This is known as the “common” screw and it’s usually black (instead of brass or silver). Note that this configuration is easiest to do when utilizing the first method of 3-way circuits discussed previously in our ‘Wiring a Basic 3-Way Switch’ article or diagram. Sometimes it is handy to have an outlet controlled by a switch. If you find the second traveler shows continuity with the toggle in one direction and not the other, the switch is probably functioning properly. A neutral wire will never be connected to standard 3 way and 4 way switches, although some smart switches and timers may make use of a neutral wire to operate the device. ♥️ Electrical Problems and Solutions Guide ♥️ … your Online Help with Troubleshooting Anything Related to Electrical Appliances and Devices. 3 way light switch with power feed via the light (two lights) The power, cable C1, joins the circuit at the light fixture F1.
