A continuous cable passes through the switch fuse, removing hot electrical joints and enabling rapid pyrotechnic cable severance in aircraft.
A cylindrical connection tube around a continuous cable removes hot detachable joints, while a pyrotechnic blade severs the line reliably.
Granular arc-extinguishing material and a fuse element crossing piston motion help suppress arcs and shut down overcurrent paths faster.
A piston gas passage vents combustion gases into the breaking chamber to prevent recoil, cut pressure peaks, and preserve insulation resistance.
A combined fusible element and pyrotechnic interrupter enables rapid circuit disconnection across fault levels while suppressing electrical arcs.
