What This Product Does
Located at the handbrake lever assembly, the contact switch changes the warning-light circuit according to the position of the lever. This allows the dashboard indicator to show when the handbrake is engaged.
Functions
- Detects the position of the handbrake lever
- Controls the handbrake dashboard warning signal
- Replaces an aged, worn or inconsistent contact switch
Technical Details
- Brand: OE Match
- Product type: handbrake warning-light contact switch
- Reference number: 90161352120
- Installation location: parking-brake lever assembly
Symptoms of Fault
- Handbrake warning light remains illuminated after the lever is released
- Warning light does not illuminate when the handbrake is applied
- Intermittent operation when moving the lever
- Warning indication changes over bumps or through vibration
- Visible wear, contamination or poor alignment around the switch contact
Why Replacement Matters
A worn or misaligned switch can give an inaccurate indication of handbrake position. Replacement helps restore consistent warning-light operation, although the lever mechanism, wiring and connector should also be inspected before fitting.
FAQs
- Could another fault cause the warning light to stay on?
Yes. Some vehicles use the same warning lamp for more than one brake-related signal, so the brake-fluid level, wiring and associated contacts should also be checked. - What should be inspected before replacement?
Check the switch position, handbrake lever movement, electrical connection and nearby wiring for looseness, corrosion or damage. - Why can the fault be intermittent?
Wear, contamination, vibration or poor contact alignment can interrupt the electrical signal as the lever moves.
Check fitment for your specific vehicle (model, year, engine) before ordering.
