This handy switch lights up when there is power to your LEDs. When you turn off the switch the light inside the switch goes out, and your lights also go out.
We have two options, a 3-12 volt AC/DC and a 7-19 volt AC/DC version. Select the 7-19 volt version for your Model Train power supplies.
The switch is threaded so it can be mounted in your panel. This switch can run from 1 - 50 LEDs.
The thread diameter is 0.5 inches.
