3 Way Switch Power To Light First. For this type of wiring you can use relays or switches by Cooper or Linear which do not require a traveler. This is a reasonable method for cases with multiple switches in the same box.
Three-way switches allow for controlling a light fixture from two separate locations, these are Three Way Switch Wiring with Light Middle. For this type of wiring you can use relays or switches by Cooper or Linear which do not require a traveler. These first three wiring diagrams in this series will help you identify the power feed and the switch wiring leading to the light fixture.
The hot source is spliced to the white wire (which should be marked as being hot with black.
The first is an outline of what you should see.
On the power coming in from the panel, you would connect that black Enjoyed your video on the three way switch. Understanding how the circuit works satisfies curiosity. For this type of wiring you can use relays or switches by Cooper or Linear which do not require a traveler.
