Pyroswitch โ€“ Protection in milliseconds
Safety in crash, other accident or fault

Pyrotechnical safety switches and closing devices. The Autoliv Pyrotechnical Safety Switches - PSS disconnect the power source from the circuit board in less than a millisecond.

Safety in case of crash, other accident or fault.

  • Triggered by eg. airbag control unit or Battery management system
  • The Autoliv Pyroswitch (PSS) disconnect the power source from the circuit board in less than a millisecond

Pyroswitch โ€“ Reliable safeguard against motor vehicle fires caused by short-circuiting

Pyrotechnic safety switches (PSS) disconnect the circuit safely and reliable, triggered by the airbag control device or BMS and before a short-circuit can occur in the circuit as a result of vehicle deformation. Airbag initiators that have been proven millions of times are used in our pyrotechnic-driven PSS disconnection systems. The complete initiation circuit, including the line and initiator are continuously monitored by the controller for functionality. After the initiation pulse, disconnection takes place without any other external aid.
