ABSTRACT:
A submergible ignition device for a submarine explosive cable cutter adapted to cut the anchoring chains and steel cables of sea mines by detonating an explosive charge. A detonator is mounted in a housing and detonates an explosive charge when impacted by a spring-biased ignition needle. A driver rod is connected to a cotter safety pin. The driver rod coacts with a shear plate which is punched through by the driver rod when the latter is impacted by a predetermined force. A spring-biased blocking rotor having a built-in detonator is adapted to coact with an ignition needle. The blocking rotor is released by the action of the driver rod. A water pressure safety device also coacts with the blocking rotor and includes a dummy position setting device. All of the safety devices are operatively connected to ensure that said detonator can only be triggered after the safety devices have been positively moved to their unblocking positions.
