How to wire up an Illuminated Vandal Resistant Switch?

I have a momentary vandal resistant swittch which i intend to use in an electronic project, what i would like to know is in order to get the LED to light up once the switch is turned on... There are 5 pins the 2 on the the outside are the + and - these are for the LED itself and the 3 in the middle are for the switch.. How do i wire the pins to get the desired effect?
