The mine is circular and has a very rounded appearance, with a central metal cap that covers the mine's safety device, a large screw. The mine is unusual in that it uses five igniter/fuzes linked to a central detonator by a series of flame tubes. Sufficient pressure on the top surface of the mine causes it to press down on one or more of the igniters compressing a spring and allowing two steel striker retaining balls to escape releasing the striker, which is forced upwards by a second spring. The striker hits a percussion cap at the top of the igniter, the flash from which travels along a flame tube to a metal chamber in the centre of the mine. If the safety screw is removed then the flash is free to ignite the detonator, which in turn detonates the main charge.
