SPST Automotive Round Rocker Switch w/Blue LED 12V
how to hook up wiring there is a plus sign then an A and then some horizontal lines I figure the plus is the hot what are the other two?
The plus is the positive voltage (live hot), the "horizontal lines" is the ground or negative, and the "A" is the switched positive. The ground (gold colored) tab needs grounding for the green LED to light up when on.

Wiring when switching ground instead of positive?
I need to use the switch to switch ground rather than 12v positive. Will led work if i have "+" and "A" hooked to ground and the horizontal hooked to 12V positive or will the polarity cause LED not to function? (if so i'll just use a relay in conjunction)
I doubt the led will work unless they have a rectifier for it in there. I wonder how easy it would be to open the switch up and flip the wires on the LED.

will these switches work in a wet marine environment??
Not for long. Do yourself a favor, use only marine rated switches, which have all copper contacts. They cost more however they will last.

Is the actual data sheet available?
Will this seat correctly in a 1/4" thick panel?Is it possible to use at a higher voltage and derate the current?A manufacturer's datasheet would help answer these questions.
My experience with switches and other panel mount has shown 1/8" is the normal panel thickness. The ribbed and tapered locks on the side may work with a 1/4" panel however may not hold tight without the help of a relief in the panel or a little epoxies. As far as the voltage is concerned most switches will handle 125-250 volts no problem. The led will have to have another resister added if the voltage is above 12-14.7 volts D.C. If you use it on an A.C. circuit you will also have to add a diode to convert to D. C. I personally use a resistance decade box and start with max. resistance and switch resistance lower until I get the result I want. Hope this helps.

The picture shows 16A but description says rated 20A which is correct?
This product is rated for 16A maximum at 12VDC. I apologize for the error in our description, we will have it corrected right away.

So I didn't plan it out... I bought this switch for 18.5V DC power supply. Is there something I can do so the little LED won't fry? Perhaps a resistor on the ground terminal, or something? 12V regulator?.....
I think a 470 ohm resisitor on the ground terminal should bring down the voltage enough.If you really wat to play it safe you can go with a 620 ohm or even a little higher. The led may start to look dim if you go with too high a value, but should be ok up to 1000 ohms.
