Sensor-based Controls

Switches or assemblies for triggering electrical functions

Usually functioning on the on-off principle, switches open or close the electric circuit in which they are installed, with actuation always leading to a specific switching state.

Our sensor-based control elements operate contactless and are therefore resistant to wear. They transmit the switching signal by means of proximity sensors upon the actuation of the switch or pushbutton.

Usually combined into one assembly, key switches, rotary switches, and steering column switches are all examples of control elements based on sensor technology.

Because these switches feature contactless operation, they are particularly well suited for settings with high levels of dirt or moisture.

Pushbutton Switches

Gear selector switches for automatic transmissions for controlling the continuous-neutral-reverse gear steps

While vehicle transmissions used to be shifted purely mechanically using the gear stick via a gear linkage or cables, today the DNR switch assumes the function of the gearshift in electrically connected automatic transmissions.

Our DNR switches can be optimally positioned in vehicles so that they ergonomically adapt to the driver's seating position.

Due to their relevance to safety, the highest requirements are placed on DNR switches. Therefore, our DNR switches fulfill the requirements of the international Automotive Safety Integrity Level C (ASIL-C) standard.

Steering Column Switches

The central control element in a vehicle

Steering column switches are controls mounted on the steering column of vehicles and are used to control an entire range of functions. Thus, they can trigger functions by tangential movement with detent or jog functions (e.g., turn signals), by pulling (e.g., headlight flasher), or pushing with and without detent (e.g., high beams). Other functions include cruise control, intermittent windshield wipers, warning lights and retarders in commercial vehicles.

Besides being resistant to wear, our sensor-based switches are designed for heavy loads and adverse environmental influences (e.g., sand, dust, and water). This makes them particularly suitable for use in commercial vehicles.

Rotary Switches

Switches for adjusting the lights and other functions in a vehicle

The rotary light switch is one of the classic controls in vehicles and its actuation unambiguously leads to a particular switch status.

The basic version of the three-mode switch governs the parking lights and driving lights. However, some switches are designed as rotary-pull multi-switches, which can be used to operate other light functions such as fog lights and rear fog lights, as well as the marker and position lights on commercial vehicles.
