Hi Shane
The switch is a stand alone Normally Open (NO) switch and you can do what you like with it within current limitations. LED current would be OK.
If you just want to light a LED…The wiring could look something like this.
Power - current limiting resistor - LED - one side of switch. Other side of switch - Ground.
The components can be put in any order anywhere you like in the circuit as long as they are in series.
