Found a lost switch

I was plugging in my scanner this afternoon, and I noticed a switch hanging down under the dash. I do not know where this goes, and it has a red top. It is a momentary push button switch. I will try to get a picture of it.
Anyone know what it might be for?

Valet switch from past alarm system?

I was thinking something along those lines. Perhaps something aftermarket. A quick glance did not show me much, but it appears to be part of stock wiring.

Most likely aftermarket unless you see a hole in your dash.

My first thought was that it might be for the traction control. The button does not do anything on the dash, so maybe it came loose and fell. But that is a long way to fall, and i am not sure it could get up that high. Plus I doubt GM would use a setup like that, the switch would be completely integrated.
