Steering Column Modules

From steering column switches to complete,
integrated modules

KOSTAL have been delivering steering column switches to the automobile industry for over 50 years. From the first simple mechanical switches to operate the direction indicators and windscreen wipers, these devices have developed into complex mechatronic modules. In Europe, KOSTAL are the market leaders in this product sector with over 30% of the business.

The KOSTAL product spectrum extends from combined steering column switches for compact cars, where proven contact systems are used to switch high-power applications, to tightly-integrated "highend" steering column modules in premium class vehicles, with connections to the vehicle bus systems.

Mechatronic integration

In addition to standard components such as direction indicator switches, windscreen wiper switches and rotary couplers, complex steering column modules contain an electronic unit to monitor the vehicle's steering angle, information from controls mounted on the steering wheel, cruise control and gear selector systems.

Steering angle sensors

KOSTAL steering angle sensors cover the entire range of requirements demanded by present-day and future vehicle safety systems. In addition to ESP and AFS (active front steering) systems, they support modern sleep detection systems, parking aids and other comfort systems. KOSTAL develop and produce low-cost, incremental measurement sensors as well as absolute measurement steering angle sensors with a resolution of 0.1°. These can be supplied as independent, standalone sensors or they can be integrated in the steering column module.

Platforms to achieve the benefits of scale

Scaled architectures by KOSTAL enable designs to be used across different vehicle ranges. This results in lower investment costs for our customers while maintaining the quality of KOSTAL steering column modules.
