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.

North America – US: 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 (US) or 3-Way (Intermediate) Switch is a DPDT is a “Double Pole Double Throw” switch having four terminals.
