HOW TO WIRE A 4 WAY SWITCH WITH LIGHT | WIRING CONNECTION | WIRING DIAGRAM
What is 4-Way Switch and 3-Way Switch – NEC & IEC?
There is no difference between 4-way switch (NEC) and 3-Way switch IEC e.g. it represents the same thing.
It is known as the 4-Way Switch or Crossover Switch. The pair of wires connecting the two switches (4-Way & 3-Way) are known as travelers.
UK, EU & IEC following Countries: It is known as 3-Way Switch or Intermediate Switch. The pair of wires connecting the two switches (3-Way & 2-Way) are known as strappers.
In short, a 4-Way Switch or 3-Way (Intermediate) Switch is a DPDT is a “Double Pole Double Throw” switch having four terminals.
4 – Way Switch – DPDT, Double Pole, Double Throw
Difference Between 4-Way and Double Pole Switches.
Both 4-Way switch and Double Pole switch look similar and have 4 terminals screws The device rating differentiate them. Alternatively, the switch terminals can be tested using a multimeter in the continuity test mode.
4-Way switches are rated for 120V – 277V, while double pole switches are rated for 220V to 240V.
4-Way switch divert both wires when switch position is changed, while double pole switch turns ON or OFF both wires.
When switch position is changed, the 4-Way switch diverts (interchanges) both wires while double pole switch turns ON or OFF both wires.

What is DPDT Switch?
DPDT (stands for Double Pole Double Throw) switch is used to control two different circuits at the same time e.g. home appliances such as lighting circuits etc. Due to the common lever, it is used to control a single operation either ON or OFF between two electric circuits such as corridor or staircase wiring installation where a lighting point is controlled from more than two places.
DPDT switch has 6 terminals where 2 of them are used as common while the rest are used as travelers or signal pins.
What is Intermediate Switch?
Intermediate switch is known as 3-Way switch in the UK and IEC following countries, while it is known as crossover or 4-way switch in North America and .
The 4-way switch has four terminals (for travelers wires) plus ground terminals in the US. While in the UK, it has only four terminals namely L1, L2, L3 and L4.
The main four terminals are used to divert the flow of electric current from one position to another. For this reason, 4-Way switches (intermediate switches) are used to control a single circuit from more than two locations such as 2-way & Three way switching circuits, hallway & corridor wiring, hostel wiring, hospital wiring, tunnel wiring, godown wiring, staircase wiring etc.
Intermediate (or 4-Way Switch) can be used to control a lighting point from any number of locations. For example, if we need to control a light bulb from six places, we will need four numbers of 4-way switches and two numbers of 3-way switches.
The following fig and gif shows how is a 4-way switch working with 3-way switches to control an LED lamp from three different locations (alternately, 3-way switch wired with 2-way switches to control a lamp from 3 places – according to IEC).
