Text copied from : TM 9-1985-6 -Italian and French Explosive ordnance- March1953:
The mine consists of a rectangular pressed-steel base plate, to which is welded the explosives container, a thin pressed cover. In the top of the explosives container is a single socket for igniter , detonator and primer. The lid is hinged to the base plate along one side, while two wingnuts are provided on the opposite side to hold the lid shut. The igniter is similar to that fitted in the French light AT mine. Igniters of either type may therefore be fitted as follows:
Model 1935: Material of body and striker-steel, material of cap and detonator assembly--brass.
Model 1936: Material of body and striker-aluminium, material of cap and detonator--aluminium.
In arming the mine , the plug protecting the igniter socket is removed and the primer is placed in position; this latter consits of a small circular metal container with a central hole to recieve the detonator. The igniter, with detonator is then screwed in place.
The igniter functions when a load on the mine crushes the cover and, descending onto the striker head, shears the igniter pin. A strong steel spring then forces the stiker onto the cap, thus firing the detonator, primer and mine. The igniter is normally supplied with a loose metal safety collar. This collar is placed in position on the head of the igniter body during transportation to prevent any load falling on the striker head.
