What is this?

Hey everyone I'm new to the site and bought my first duramax today. 2015 Silverado 3500hd cab and chassis 4x4 with a flatbed. Anyway does anyone have an idea what this button is? Even asked the dealer I bought it from and he didn't know

It's a air operated PTO switch. Used on fire trucks to switch the transfer case from road to pump. If it's on a Duramax, it probably just activates a PTO by air pressure.

The switch I was talking about was the yellow knob.
The flat one with the picture on it is probably an electric switch for the PTO or transfer case. If it's a flat bed, it might hydraulically tilt.
