Mack Ignition Switch

The Mack Ignition Switch controls the electrical sequence that brings the engine and dash systems to life. When the key turns, the switch routes power to ignition circuits, accessories, and starter engagement in a timed order. A worn switch can interrupt that sequence, causing hesitation at startup or intermittent power to the cab electronics. Replacing the switch restores predictable key response and steady engine cranking. For vehicles that require consistent ignition control at every turn of the key, the Mack 25120246 reestablishes that command point within the steering column.
