T430s power jack help

[astrogamer]

I was replacing the power jack on my T430s since the old one was basically broken. However, when I was putting the new one in, the black switch next to the charging port fell off. It can slide back on but, it seems like it will fall off easily. Is there any simple way to attach it or do I have to try and get a replacement?
