Commonly used in launch vehicles, tactical missiles, cargo and parachute deployment, and payload release mechanisms, a pyrotechnic device is a one-time use type of cutter. Activated by an electric signal, a small explosive charge within the device fires creating a high-speed, shearing effect that severs electrical circuits, opens or closes a valve, or releases and separates bolted connections and joints.
