Tappet Switch
The Tappet Switch operates through a mechanical tappet action that triggers an instant on/off signal to the ECU or electrical components. Built with a durable internal mechanism and a sealed, moisture-resistant housing, it performs consistently even under heavy vibration, heat, and exposure to dust and contaminants typical in commercial vehicle environments.
Its robust construction ensures long-term reliability, fast response, and stable performance across varying operating conditions. By maintaining precise communication between mechanical inputs and electronic outputs, the Tappet Switch enhances overall vehicle safety and system efficiency.
