Illuminated Rocker Switches

Illuminated rocker switches are typically used in industrial settings to highlight when a power source or a device is switched on, although are found in some consumer products, too. Illuminated rocker switches can provide an additional visual cue as to whether something is switched on or off and enable such a check to be done from greater distances.

How do illuminated rocker switches work?

Illuminated rocker switches work in the same way as regular rocker switches. When the switch is closed, this completed the circuit and allows power to flow to a device or switches a device on. Illuminated rocker switches have a transparent case and LED, fluorescent, or neon lamp that lights up to show it is switched on.

Why use illuminated rocker switches?

Illuminated rocker switches allow you to easily see if a device is powered up and switched on, making it easy to identify if it isn’t working. These switches can also work as “warning systems” to highlight devices that work in silence or intermittently are switched on and may be in operation.

How do you know if your illuminated rocker switch isn’t working?

The most obvious ways you can tell if your illuminated rocker switch isn’t working correctly is if the switch is on and your circuit or device is operational without the switch being lit, or if the light stays on even when the switch is off.

How can you test an illuminated rocker switch?

If you’re unable to tell whether your illuminated rocker switch is working when it is in place, you can test whether it’s the faulty component within your circuit with a multimeter.
