So in this case, do you have to provide a discreet voltage to light up the switch rocker for night illumination. And, for the dependent "ON" indication, where does that power come from?
Yes, you must provide a 12v source to the LED/lamp to illuminate. I used my plane's main buss voltage protected by a circuit breaker. A Double Pole/Single Throw (DPST) switch would work in your example - 1 pole to switch & provide power to the LED and the other pole to switch & ground your circuit.

I used the carling rockers and VPX. I didn't run a dimmer at first and the switch lights were way too bright. I rewired through a dimmer a year into it and now its perfect! I am just switching ground so not worried about the switch but there is a lot of plastic. I wouldn't want to run any amperage through the carling rockers.

Do you have these switches installed? If so, pictures perhaps?


Thanks

Default Not specifically, but

Not specific switch pix but a couple closeups from a panel upgrade; plus a naked one. They engrave nicely. Have engineering data crops if desired.

I had these made as they're the closest dims to the Rocker breakers (bottom right of pic 2) common to that vintage. You've probably flipped one in your past. The Cessna split Alt/Master switches are the same family.


You can PM me and reach out through the forum here.

In a HIGH amp draw situation, I may use DC switch.

Labeled versus rated. Only speaking for the ones I’ve posted. Labeled with the AC rating obviously. Eng drawing and product catalog list the 15 amp DC rating.

From my experience with industrial grade equipment (not aerospace), AC rated devices can have real issues with DC. Not always related to power throughput as I would have thought. Not unusual (probably typical) that the issue is with the “break” versus the “make”. The potential never crosses null so contacts can stay closed when the opposite is desired/actuated. More true in relays and instrument switches from my experience than a manual switches but certainly possible and probably more likely the more miniaturized something is. There’s also contact erosion down the road. Guess my real point is to use devices I.A.W. the OEM’s rating. I’m ME, not EE so I rely a lot on vendor literature and their reps for my info. Long a$$ rationalization over, sorry.

Default Found.....

I found the switches I need. Thanks for all the help. Most switches referenced here are to tall for my space.
