Switch on accellerator assembly

[sealandsky]

While performing a detailed vacuuming on the floor of my 2019 Yukon Denali I discovered that there is some sort of momentary switch that is "clicked" just shy of full pedal travel. It does have an audible click when pressed. The problem is that with my Weathertech 3D floor mat installed, the pedal travel is slightly restricted and I don't hear the "click" (although I feel that if I press hard enough that I'm at least partially activating the switch).

Does anyone know what this switch is for?
