An engagement switch is a component located at the clutch and will typically be found in vehicles with four-wheel drive capabilities. This component functions to control how the front axles of your vehicle engage. As such, when you turn on the switch, your vehicle's front differential is supposed to engage so that the front wheels of the car receive more power. Motorists with four-wheel drive vehicles will typically not pay much attention to this switch, as it tends to function without any incidence for a significant amount of time.
