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

Product Information
Clutch Pedal PSM / Cruise Switch.
This clutch pedal switch sits behind the clutch pedal and communicates pedal position to the vehicle’s electrical systems. When the clutch pedal is depressed or released, it relays that signal to the starter, cruise control, PSM (Porsche Stability Management), and other relevant systems that depend on clutch position information. Designed to match the original part’s electrical characteristics, housing, and fitment, it installs into the factory mounting point without modification.

Diagram Ref No 17

The clutch pedal switch ensures the vehicle can only be started when the clutch is depressed, enhances safety by providing input to cruise control and transmission logic, and informs stability and traction systems of clutch engagement status. A properly functioning switch prevents starter engagement unless conditions are safe and contributes to smooth operation of related vehicle functions.

Function:
As a microswitch mounted near the clutch pedal, this part closes and opens its contact in sync with pedal travel. That change in contact state is interpreted by the vehicle’s ECU and safety systems, enabling starter activation, cancelling cruise when appropriate, and helping ensure proper control logic throughout the driveline. Its OE-match design ensures consistent signal quality and long service life in typical operating environments.

A failed clutch pedal switch can prevent the engine from starting, inhibit cruise control function, trigger false warnings, or interfere with stability control inputs. Because it’s a safety-critical sensor tied to multiple control systems, replacing a worn, intermittent, or failed switch with an OE Match part ensures proper system response and restores reliable interface between the clutch and vehicle electronics.

When to replace:
•  Engine won’t start unless specific clutch pedal positions are met
•  Cruise control doesn’t engage or disengages unexpectedly
•  Clutch position signal feels intermittent or inconsistent
•  Dashboard warnings related to clutch/safety logic
•  During clutch or pedal assembly service

About Brake & Clutch Switch

Ensure the reliability and responsiveness of your Porsche’s braking and clutch systems with genuine and aftermarket brake & clutch switches from Design911. These vital electrical components ensure accurate pedal signal transmission, improving safety, drivability, and system performance.

What They Are & What They Do
Brake and clutch switches are small, yet crucial electrical sensors located near the pedal assemblies.

  • The brake switch activates the rear brake lights and may also interact with systems like cruise control, ABS, and stability management.
  • The clutch switch helps manage engine start permissions, cruise control disengagement, and gear-change smoothness on manual and semi-automatic transmissions.

Together, they ensure precise coordination between driver inputs and your Porsche’s electronic systems, contributing to smooth shifting, reliable braking, and enhanced safety.

 
Why They Fail
These switches can degrade over time due to constant mechanical use, electrical contact wear, heat exposure, or moisture ingress. Symptoms of failure include non-functioning brake lights, difficulty starting the car, cruise control faults, or inconsistent clutch operation. Corrosion, contamination, or worn springs can cause the switch to stick, delay, or fail entirely.

Why They Should Be Replaced
A faulty switch compromises vehicle safety and drivability, potentially disabling key systems like brake lights or start interlocks. Replacing worn switches restores proper pedal feedback, system coordination, and safety compliance.
Design911 supplies genuine Porsche and premium aftermarket switches designed for perfect fitment, durability, and accurate electrical response, ensuring your Porsche performs exactly as intended.
