For 4 way switch wiring you will need two 3 way switches one at each end and then as many 4 way switches as you want in between.
2 way switch vs 3 way switch.
Wall switches used to control ceiling light fixtures or other fixtures come in three types.
There is definitely a difference between single pole light switches and 3 way light switches.
Before jumping straight into the feature specific table let s go through some useful information.
When it is turned on the two terminals are connected and when it is turned off the contact between the two is broken.
We dive into the differences and help give you a better underst.
I will show how to wire 3 switches however you can add as many 4 way switches to the circuit as you need or want.
In a normal switch the two terminals are either connected as shown or disconnected.
When they are connected the switch is on in a three way switch the top terminal connects to one or the other of the bottom two terminals.
A one way switch basically operates as a make or break switch.
So what is a 2 way switch.
A three way switch has no marking because there is no consistent on or off position.
2 way vs 3 way switch.
This type of switch must be combined between two three way switches to form a circuit.
Here 1 terminal is the input and the other two are used as outputs.
The 2 way switch or single pole double throw switch is a three terminal switch.
Take a look at the switches in your home.
A one way switch only has two contacts while a two way switch has three.
While more uncommon this is a good option for large rooms with several entrances.
The actual terminal configuration on a three way switch depends on the manufacturer.
For example a long hallway or stairway might use a pair of three way.
2 wire cable runs from the light to the first switch and then 3 wire is run between all the switches.
Single pole switches with one switch controlling one light are marked with an on and off position.
Most common is the single pole switch the type used to control a light fixture from a single location the next most common is the three way switch which is commonly used to control a light fixture from two different locations.
The on off can change depending on the position of the second three way switch.
A four way switch is similar to a three way except it has four terminals plus a ground terminal and controls one fixture from three locations.
Remove the three way switch from the circuit start with the three way switch that will be removed.
It s okay if this is too complex for you.
All three way switch and 2 way switch wiring diagrams have the same basic components.
Wires consisting of a line a load a neutral a pair of travelers and two 3 way switches.
