ABSTRACT:
A mechanical inertia switch in a housing has an elastic tongue with an inertial mass as well as a contact piece. The elastic tongue has a stable neutral position and can be moved in the direction of the contact piece against a force, for example a magnetic force or a force due to preloading of the elastic tongue, which acts in addition to a spring force of the elastic tongue. The compact mechanical inertia switch has a small number of components and short switching times. The elastic tongue is prevented from oscillating. It is thus possible to use the mechanical inertia switch as a safing sensor for detecting side impact.
