Tappet Switch
The Tappet Switch monitors engine tappet movement and helps regulate related control functions.
This switch is designed to detect tappet position or movement changes and send accurate signals to the engine control system. Built with durable electrical contacts and a robust housing, it withstands heat, vibration, and continuous mechanical motion inside the engine environment. Its precise response ensures proper timing-related operations and prevents faults due to incorrect tappet feedback.
By providing reliable switching signals, the tappet switch improves engine efficiency, supports smooth operation, and helps prevent malfunctioning of components dependent on tappet movement. It plays an important role in maintaining accuracy, safety, and performance in heavy-duty commercial engines.
