HELLA 6DD 010 966-421 Clutch Position Switch

The HELLA 6DD 010 966-421 is a clutch pedal position switch that feeds a signal to the engine or transmission control unit rather than to a cruise control module directly. Depending on the vehicle, that signal can be used for anti-stall control, idle adjustment, or gear-shift timing, so exact function varies by application.

When this part fails, the usual signs are erratic idle when the clutch is pressed, hesitation on gear changes, or a related fault code stored in the engine or transmission control unit. Swapping the switch is usually the fix once it’s confirmed as the fault, rather than a symptom of something bigger.

This listing is an aftermarket replacement, not a genuine dealer part. Before ordering, check it against your original part’s EAN or your vehicle’s OE catalog reference rather than the vehicle description alone. Switches like this are shared across several models within a platform, so an exact number match matters more than the model name.

Installation is a straightforward unplug-and-replace job on most applications: disconnect the wiring connector, remove the old switch (usually a bayonet twist, a threaded body, or a single retaining clip depending on the design), and fit the replacement in reverse order. No calibration is normally needed, though it’s worth testing the function it controls before buttoning the panel back up.
