All German igniters are capable of being screwed into German made-up charges and mi-nes (in some cases by means of an adopter). They can also be attached to safety fuze by means of an adaptor. In all cases the igniter fires a percussion cap.

This is the 3-pronged pressure igniter most often used with the "S" mine (see page 55). Pressure required, about 15 lb.

This igniter is made in two sizes, the larger being made of aluminum and painted brown, the smaller being unpainted brass. The larger needs a greater pressure to fire. They are chiefly used in improvized mines and booby traps and in similar places to our own pres-sure switch.

This igniter can be recognized by the large ring attached to the end, and may be found with "S" mines and in booby traps.

Action is very similar to our pull switch and it is used with trip wire in the same way. Used with "S" mines either singly or in pairs, and in booby traps.

Used with the "S" mine this is a variation of the standard 3-prong pressure igniter, which fires and electric detonator in the mine. This set up is usually found with one mine ope-rated by any of 18 igniters used in two chaius of 9, thus increasing the radius of action of the mine.
