Power Button Super Sensitive Needs Replaced

I have a i pod touch gen 16gb, not jail broke or hacked. I have a hardware problem with the power switch, it powers on or off (red slide) with the slightest touch of the button. The power button is super sensitive. I can hold i pod and jerk my hand once and get the i pod to power up. I've taken the back off and have tested the switch, there is a problem with the power button. Where can I get a replacement power switch? The adhesive holding the power ribbon to the back case is that anything special? I read the back replacement but it doesn't say anything about gluing the power ribbon to the back of the case.
