The body is a black plastic with the LED built inside. There are two contacts for the button and two contacts for the LED, one marked + and one -. The forward voltage of the LED is about 2.2V so connect a 220 to 1000 ohm resistor in series just as you would with any other LED to your 3V or higher power supply.
This particular button has a red body and LED and is latching on/off. The two switch contacts are either connected or disconnected. When you push the button they will switch from one to the other, like an on-off switch. The LED is separated from the button, so you can make it light up when on, light up when off, always lit, etc.
