Parts Express SPST Automotive Round Rocker Switch with Blue LED 12V
running this switch after the power supply for the lepai 2020+ amp (12v 3a) the light gets extremely hot….is it even a led? switch is WAY too hot.
This switch does use a small LED and resistor. They will normally get pretty warm depending on the current flowing through the switch.

The switch is rated for 16A max. But what minimum current is required to light the LED? (I have 12VDC 1.5 battery supply). Thank you!
The LED will require very little current in order to be illuminated. Most are 40-60 mA.

how would you wire this switch to a TA2024 amp that is being powered by a battery pack? If it cant, what is the best switch to use?
I would recommend a simple SPST switch without illumination for an application like this. It simply wires in line with the positive power input.

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.

What size connectors are required to hook up to the terminals?
These terminals are 3/16" wide.

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.
