A pilot light switch is an electrical switch that includes a small indicator light.
This light illuminates when the circuit is closed and the switch is in the “on” position.
The pilot light serves as an indicator to show whether the connected load (such as a light fixture or other appliances) is powered on or off.
These switches are designed to enhance safety and convenience by providing a visual indication of the circuit status.
Whether you’re illuminating a dark hallway or ensuring that outdoor lights are on, a pilot light switch can be a practical addition to any electrical setup.

The switch itself operates just like a regular switch, allowing you to turn a circuit on or off by physically toggling it.

Inside the switch, there’s a circuit dedicated to powering the indicator lamp. This circuit is usually separate from the main circuit controlled by the switch.

When you connect the switch to a power source and a load (like a light or an appliance), electricity flows through the switch.
Additionally, a small amount of power is directed to the indicator lamp circuit.

When you toggle the switch to turn the circuit on, electricity flows through the indicator lamp circuit as well.
This causes the indicator lamp to light up, indicating that the switch is in the “on” position and the connected device is receiving power.

When you toggle the switch to turn the circuit off, the electricity flow to the indicator lamp circuit is cut off, and the indicator lamp turns off, indicating that the switch is in the “off” position and the connected device is not receiving power.
