Control Elements
Switches or assemblies for triggering electrical functions
Switches generally work according to the on-off principle and open or close the current circuit in which they are installed, with actuation always leading to a specific switch status.
Our sensor based control elements are contactless and thus free from wear as they transmit the switch signal via proximity sensors once the switch or button is actuated.
Button, rotary, and steering column switches are typical examples of sensor based control elements that are usually combined to form an assembly.
As these switches feature contactless operation, they are particularly suitable for use in settings with high levels of dirt or moisture.
Pushbutton switch
Where vehicle transmissions once required mechanical switching of the gear selector lever via a rod or hoist in order to change gears, the DNR pushbutton switch now largely assumes the role of the shift lever in modern electrically connected automatic transmissions.
Our DNR pushbutton switch can therefore be positioned to provide maximum ergonomic benefits for the driver seated in the vehicle.
DNR pushbutton switches are subject to very strict requirements reflecting their important safety role – and ours comply with the international Standard Automotive Safety Integrity Level C (ASIL-C).
Steering column switch
Steering column switches are control elements that are attached to the steering column of a vehicle and control a whole host of functions. They can trigger other components through latching or jogging functions via tangential movement (e.g. turn signal), through pulling (e.g. flasher), or through pressing with or without a latch (e.g. high beam). Additional functions include cruise control and interval windshield wipers, plus the retarder and warning lights in commercial vehicles.
Our sensor based switches are free from wear and suitable even for high loads and challenging environmental influences (e.g. sand, dust, and water). This makes them particularly suitable for deployment in commercial vehicles.
Rotary switch
The rotary light switch is one of the classic control elements featured in vehicles, with actuation always leading to a specific switch status.
The basic version features three settings and is used to control the driving and parking light. However, other switches designed as rotary/pull multi-switches can operate additional light functions such as fog lights, rear fog lights, marker lights, and position lamps on commercial vehicles.
