The four leads on a regular push button are just redundant, they are really just there to hold it to the PCB better. Just attach two AA batteries to one wire of the switch and an LED to the other side, then back to the batteries, if the button works properly, the LED will light up when, and only when, you press the button. If it's not lighting, odds are you either have dead batteries or the polarity is wrong (you have to LED backwards, the short leg should attach to the - side of a battery. Oh, and make sure it's a visible LED, not an IR one from the kit, as you can't see those anyway )
To solder it to the kit board, hold the board to the LEDs are on top (top as in north on a map) then solder one button wire to either of the top holes for the push button, and solder the other one to either of the bottom holes. The holes are connected horizontally with copper traces, so it doesn't matter which hole you solder them into as long as one is on top and the other is on the bottom.
Hope that helps!
