Breaker BootCamp Study Guide


A 4-way switch controls one load from three or more locations.


It is installed between two 3-way switches.





What It Does



A 4-way switch redirects traveler paths between two 3-way switches, allowing additional control points without changing end-switch logic.





Where It’s Used



  • Stairways with a mid-landing

  • Large rooms with multiple entry points






One Critical Rule



A 4-way switch never goes on the end of a circuit.

If it’s not between two 3-ways, it’s wrong.





Why Breaker BootCamp Teaches This



The Breaker BootCamp Study Guide eliminates guesswork in multi-location control so the Breaker BootCamp course stays focused on clean wiring, correct logic, and zero callbacks.
