Scope of application

Our products contribute to your safety in the vehicle.


The signals from our belt buckle switches are evaluated by the control unit and, depending on occupancy and vehicle type, used to control hold-on, start / stop, handbrake and classic sound and light warning.


In addition to the normal warning function, a diagnosable belt buckle switch can be used in a traffic accident to control the airbag.
