Three way and four way switches

How to use - way switches and - way switches to control lights from two or more locations. A complete tutorial on controlling lights with multiple switches. How - way and - way switches work, an animation showing how two or three switches can be used to control the same light. In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.


Understanding how the circuit works satisfies curiosity.

I think you can tweak this to make it work.

As for the software use it was .

A 4-way dimmer diagram is included as well as an arrangement to control the lights from four different points. This page shows several variations of using three or more switches to control lights. In every circuit, you may omit any or all of the - way switches if you need fewer switches.


Similary, you can add as many additional - way switches between the - ways as you like, just following the same . Four - way switches are used to control lighting from three or more locations. Learn more about how the different switches work. Do you know how - way - way multiway switching works? For instance in my garage, I can turn on and off the lights from . Sure, a - way is essentially two - ways in one device.


Connect travellers as usual, then connect the power or light wire to one of the remaining terminals, leaving the other empty. Background Information (if anyone cares). The following illustration demonstrates the internal . Three and four way switches work by opening and . There are several ways to wire three way switches , the key is to identify where the power source is located. And any defective switch or connection further . Each wire needs to be connected to the proper terminal screw on the light switches. A - way and - way switch animation, showing how two or three switches can be used to control the same light.


Here are several variations of using - way switches to control lights from two locations. Colors are shown consistent with the NEC. Before reading this page, you may want to visit - way switches and - way switches.


It is not possible to run an additional cable without major disruption to newly plastered walls.
