Operating principle of the Pyro-Switch

  1. 1.An ignition current is generated from an external signal. "One Time Energy" activates to generate gas.

  2. 2.The piston pressurized by generated gas detaches the 1st busbar, shutting down the electric circuit.
    The detached 1st busbar cut by the piston attaches the 2nd busbars to create a short-circuit.
