The present invention relates to a mine incorporating a pressure plate. Such a mine comprises, inter alia, a pressure plate, a pyrotechnic firing chain and an arming device. The pyrotechnic chain comprises a firing relay rotatably mobile in two substantially perpendicular directions to ensure alignment of the pyrotechnic chain by a double rotation of a support disc about a shaft and a mobile member about an axis. Maneuvering of an arming button ensures rotation of the mobile member; a clockwork timer device ensures rotation of the support disc. A further feature of the invention resides in the reversibility of arming, the opposite maneuver of the arming button ensuring that the mobile elements of the mine return to their intial position. In addition, an anti-blast device is incorporated in the pressure plate. The invention is applicable to anti-tank mines.

A cartridge with firing actuation of the payload comprises a case solid with a case bottom which houses a threaded member constituting an ejection nozzle, and in front of the latter a missile provided with a delay ignition chain interrupted at the level of a transversally movable slide which comes into fire transmission position only after a predetermined delay. The cartridge has in addition a striker device actuated on impact so as to ignite the delay firing chain on impact, and a stabilizer device ensuring an axial deceleration permitting the satisfactory operation of the striker on impact.
