Battery Cut-Off Housings

Product Description

In some vehicles, the battery is not located in the engine compartment, but rather in the rear of the vehicle near the fuel tank. In the event of a crash, the flow of current from the battery must be stopped immediately to prevent the fuel in the fuel tank from igniting. This can be achieved with a “cut-off” system, which isolates two contacts from one another with the ignition of a small charge.

The operating principle employed in battery cut-off systems is similar to that used in airbag ignitors.


The materials used in the battery cut-off housings are highly resistant to the environmental conditions prevailing in the rear of a vehicle. The materials used and specifications for battery cut-off systems can be adapted to customer requirements.


Battery cut-off housings and feedthroughs made with glass-to-metal sealing are suitable for all applications that require reliable, long-term transmission of an electrical signal for the ignition of hermetically sealed explosive loads. Other areas of applications include airbag ignitors.

Technical Details


To ensure the reliable hermeticity of battery cut-off housing components, glass-to-metal sealing technology is used. Please click on this page for more information.

The type of glass and metal used differs, depending on customer requirements and the type of feedthrough required. Very often, battery cut-off systema feedthroughs are produced using steel and stainless steel due to their high resistance to corrosion. In addition nickel and/or gold plating in compliance with the latest automotive industry standards are applied.
