The project you are going to be used for, don't let current go above 5 amps. Or the switch will get warm and to be burned out.
I love the switch style and feel.
Here's the details:
1. The left and right tabs in the photo power the LED. With 12.7V applied, it was using 8.1mA (0.0081A). The LED illuminated regardless of which way I ran the power through it. That amount of current will take 5 days to burn 1 amp-hour from a battery.
2. The No means "normally open", and the Nc means "normally closed".
3. "Normal" means "when the pushbutton is off". "Open" means the circuit is open and no current flows through, "closed" means the circuit is closed and current flows.
4. The power comes in through the bottom tab, and if the switch is off (button not depressed), power will flow to the top tab (right hand diagram). If the pushbutton is depressed, power will flow to the center tab (left hand diagram).
5. If you want the button illuminated all the time, wire 12V to the left tab and ground the right tab.
6. If you want the button to illuminate when the button is on, connect the center and left tabs (when power goes to the using device, it will also go to the LED power).
7. If you want the button to illuminate when the button is off, connect the top tab to the left tab (when power is shut off to the using device, the top tab will power the LED).
I'm using this to run a 24V lighting setup (2X12V LED lights in series), which should be okay in theory (the switch is theoretically rated for 250VAC), but that much voltage will burn out the LED. Thus, I'll need to find a 12V source if I want to illuminate the push button, and it will be illuminated all the time if I do that.
