Spare switch under drivers Recaro.

I recently discovered a switch dangling below my drivers Recaro and have no idea where it should go. It isn't on the passenger side is I am guessing it might be something to do with seat position for the airbag perhaps. Any help would be great?
 
That switch is for the airbag. It basically fits on the seat and there is a bit on the runner that activates it. What it is for, is people who like to sit near the steering wheel, have the seat further forward, when the seat is closer to the steering wheel and you have an accident, it deploys the airbag at a slower rate, so it doesn't cause injury. If you have long legs and sit further back you get the airbag at full blast. So if you are a short ar#e like me get it put back on.
