The OE Match Turn Signal Switch is a high-quality replacement steering column control switch designed to operate the vehicle's turn indicators and signalling functions. Manufactured to OE specifications for fit, functionality and durability, this switch restores reliable operation of the indicator system while maintaining the original appearance and feel of the vehicle's controls.
Fits:
Diagram Ref No 2
Mounted on the steering column, the turn signal switch enables the driver to activate left and right turn indicators, helping communicate intended driving manoeuvres to other road users. Constructed from durable electrical and mechanical components, it is designed to withstand years of repeated operation while delivering dependable performance.
What This Product Does:
- Controls the vehicle's left and right turn signal functions.
- Activates the indicator lamps when changing direction or lanes.
- Helps communicate driver intentions to other road users.
- Supports safe vehicle operation and road compliance.
- Provides smooth and reliable indicator switch operation.
- Integrates with the steering column control system.
- Helps maintain factory-correct functionality and driving experience.
Symptoms Of Wear Or Failure:
- Indicators fail to activate when the lever is operated.
- Intermittent turn signal operation.
- Turn signals remain on after completing a turn.
- Failure of the self-cancelling mechanism.
- Loose, worn or excessively stiff switch movement.
- Flickering indicator operation.
- Electrical contact faults causing inconsistent signalling.
- Physical damage to the switch lever.
- Dashboard indicator malfunction related to switch operation.
Why Replacement Matters:
- The turn signal switch is one of the most frequently used driver controls and is subjected to thousands of operating cycles throughout its service life. Over time, internal contacts, springs and mechanical components can wear, resulting in unreliable signalling performance.
- A faulty turn signal switch can prevent other road users from receiving clear indications of your intended direction changes, increasing the risk of accidents and potentially causing roadworthiness or inspection failures. Intermittent operation can also create confusion for both the driver and surrounding traffic.
- Replacing a worn or damaged turn signal switch restores reliable signalling performance, improves driver confidence and helps ensure safe vehicle operation. An OE Match replacement provides factory-style fitment, dependable electrical performance and long-lasting durability, helping maintain the safety, functionality and originality of your Porsche.
