Clutch Pedal PSM / Cruise Switch.
The clutch pedal safety switch signals the vehicle’s control systems whenever the clutch pedal is depressed or released. It is a critical safety device that allows the engine to start only when the clutch is engaged. It also provides clutch position feedback to systems such as cruise control, Porsche Stability Management (PSM), and transmission logic.

Diagram Ref No 17

As the driver presses or releases the clutch pedal, this switch opens or closes its internal contacts. That change in status is interpreted by the vehicle’s control modules, allowing correct sequencing of starter engagement and informing dynamic control systems of mechanical clutch state. Its precise calibration and genuine parts engineering ensure consistent signal quality and long-term reliability.

A faulty clutch pedal safety switch can prevent the engine from starting, cause erratic cruise control behaviour, trigger warning lights, or provide incorrect input to vehicle safety systems. Because it is tied to safety and drivetrain logic, replacing a worn or failed switch ensures restored functionality, correct system behaviour, and full compatibility with original vehicle control systems.

When to replace:
•  Engine will not crank unless the clutch is depressed
•  Cruise control fails to engage or drops unexpectedly
•  PSM or stability warnings related to clutch status
•  Intermittent or inconsistent clutch position signals
•  During clutch pedal or pedal assembly service or replacement
