Why are Pyroswitches (PSS) needed?

Prevention of short-circuits, caused by accidents

  • In many wire harness the starter/generator cable remains unprotected.
  • In case of a crash, damaged and unprotected cables could lead to a hazardous situations for passengers and/or rescuers.
  • Prevention of short-circuits which can lead to thermal event and burn.
  • Prevention of battery draining. Power is needed for important functions.

Background

Investigations conducted by DEKRA (Deutscher-Kraftfahrzeug-Überwachungs-Verein) establish that almost 90% of road traffic accidents cause subsequent fire at speeds above 80 km/h. The conclusion to be drawn is that the extreme deformation of the vehicle body causes an earth fault of the thickest electrical conductor, the cable between the battery and the starter / generator.

Ignition and smoldering fires

In the case of such short-circuits, there can be direct ignition caused by sparks or arcing or, equally hazardous, smoldering fires occur as a result of the enormous heat development. Apart from the hot parts in the engine compartment, the electrical energy stored in the battery forms the primary source of ignition in the car. 

Safety in the manufacturing line - for your applications, too.

Disconnection systems and pyrotechnical safety battery terminals are approved standard of the automotive industry. You can trust the experience and high quality requirements of the vehicle industry and use the PSS Pyroswitch of Autoliv.
