Pyroswitch – PSS-3 (NC)
Battery Disconnection Switch PSS-3

A pyrotechnical actuator separates the electric connection irreversibly. Pyrotechnical switches are installed in many road vehicles. It is triggered by the ECU, and is used to separate the "starter-generator-cable" from the electrical system (battery). A second circuit is disconnected simultaneously.

Product highlights

  • 0.1 milliseconds separation time
  • For hybrid and electrical cars
  • High and low circuit switching
