Question: I know there are multiple ways to wire a 3-way switch. I commonly use the standard Power......3 wire........Load technique to keep things simple but I also use a "dead end" occasionally.My question is about 4-ways. Do they have any variations like 3-ways? Or is it always going to be power in, 3wire between multiple switches, out to load?
You're right, there are indeed variations for wiring 3-way switches. As for 4-way switches, the answer is more straightforward
No, 4-way switches don't have significant wiring variations like 3-way switches do.
Here's why: Function of a 4-Way Switch
A 4-way switch's sole purpose is to act as a traveler wire switcher within a 3-way circuit. It doesn't connect directly to the power source or the load. It sits in between the two 3-way switches.
Standard Configuration
The 4-way switch always has two pairs of traveler wires connected to it. Its internal mechanism simply swaps which pair of travelers are connected to each other.
No "Dead End" Equivalent
Because of its function, there's no equivalent of a "dead end" configuration for a 4-way switch. It
must be wired in the traveler wires path between two 3-way switches. Wiring Diagram
The 4-way switch will always have two travelers coming
in to the switch, and two travelers going out of the switch.
In summary: While you can be creative with where you send power and the load when wiring 3-way switches, 4-way switches are much more standardized in their wiring configurations because their purpose is only to change the path of the traveler wires. Flag for review
