Since there's an LED inside, but only 3 pin, they're a little different to wire than most toggle
switches.
The anode (positive side) of the LED is connected through a resistor to the pin with a
'headlamp' (=D) symbol on it
The cathode (negative side) of the LED is connected to the pin with the ground symbol,
which is the pin that is sticking out the side of the switch.
The switch connects and disconnects the (+) pin and the 'headlamp' pin
That means you have a few options for wiring:
If you want to use the switch to turn on/off something, you can use the toggle to connect
and disconnect the two pins on the bottom
If you want the LED to always be on, provide 3-12V between the ground and headlamp pin
If you want the LED to be on only when the switch is connected, provide 3-12V on the (+)
pin and connect ground to the ground pin.
The protective cover will automatically turn the switch off when flipped closed, but you can
simply remove it if it isn't desired.
