I wired a rocker switch with a built-in indicator light to control a 12VDC relay. The switch works and the relay works, but the indicator light doesn't. It is attached to a proper ground. I then realized that the switch was rated for 100-125VAC. Is this why the light doesn't work and is there a solution outside of using a 12VDC switch?
TIA |

Yes thats why there's a 120volt bulb inside

I guess I assumed wrongly that there was an LED inside. Thanks!

VERY few use LED's as for the huge resistor that would be needed the bulbs are more likely

Not really,most newer rocker switches use l.e.d.s just like the lighted rocker switches sold on here. Sounds like the switch is wired improperly. Is it like this? http://www.oznium.com/rocker-switch/tech |

Yes, like the diagram, except the switch is controlling the trigger going to the relay.

Yes, it's possible. Considering the price, very possible. I'll try another and if that doesn't work, I'll buy one rated for 12VDC from Oznium. Thanks much.

Just tried another one and it didn't work. I don't know much about l.e.d.s, but would there be a different resistor in the switch to make the indicator function at 120VAC than one to work at 12VDC? The switch looks almost exactly like the one you had a link to. Here's an internal wiring diagram of the switch I have.

Just checked the spec sheet for the switch and it turns out that the indicator is a neon bulb. Probably a whole different ball game.

Hmm...well maybe that's why it's not lighting. |

Yeah pretty much.lol The Oznium rockers and others are also rated for ac like the switch he was describing too and their l.e.d. indicators work fine. I just wasn't sure as to what type of light was in his switch and come to find out it's a neon bulb. |
