I have this pen that has a red laser in it. I removed the pen and the metal casing around and I have a laser diode and it attached to a chip. At the other end of the chip it has a spring to put the positive side of the batteries too. Here is a picture (not allowed to post links so replace strings in brackets respectively):

Can someone explain why there are two wires (blue lines) that are just hanging off not touching the diode? Also, how can I get this thing to light up right? I have a 3 volt button battery, 4 other small ones, and two medium sized ones taped together lined up. When I put the positive side to the spring and press the button it doesn't light up. I am very new to this so please be nice

PS: The red square is the button.
