How does an illuminated 3-way toggle switch, advertised as "illuminated when off," determine when it is in the off position?

lThe illuminated 3-way toggle switch is designed with a built-in mechanism that detects the flow of electricity to determine whether it is in the off position.


When the switch is turned off, the circuit is interrupted, preventing electricity from reaching the switch's internal components.


The switch then activates the illumination feature, indicating to the user that it is in the off position.

This functionality allows for easy identification of the switch's status even in low-light conditions, enhancing convenience and safety.
