4 Gang Light Switch Wiring Diagram. This presentation shows the internal workings of the four-way. All fixtures will be on the same circuit.
Understanding the terms 'GANGS' and 'WAYS' when referring to electrical switches: full explanation with circuit diagrams and illustrations. Assuming that your switches will only accept one wire per terminal, it might be easier to feed them with pigtails, as Furd suggested, than to daisy-chain them with. Also included are wiring arrangements for multiple light fixtures controlled by one switch, two switches on one.
Summary: Easy to Understand Light Switch Wiring - Fully Explained Light Switch Wiring with Diagrams and Pictures with Step-By-Step Instructions to I know I have to change the gang box and I'm fine with running cable and installing plates but I'm not clear on the best way to add the wiring. ****I updated the wiring diagram with the changes I made.
