Some switches require a neutral wire because they need a continuous flow of electricity to power certain features, such as smart functionalities or illuminated displays, even when the switch is in the "off" position. The neutral wire completes the circuit and provides a return path for the current, ensuring the switch can maintain these features without disrupting the main power to the connected load. This is particularly common in smart switches that need to maintain connectivity to a network or control system.
