DESCRIPTION. The igniter consists of a steel body housing a striker and striker spring. (See fig. 272.) The striker is retained in a "cocked" position by a shear wire which runs through the striker stem and rests on the upper surface of the body. At the base of the igniter, is the percussion cap housing which extends to form a flash channel. This exten-sion bears an annular groove into which can be crimped a standard German detonator (Sprengkapsel No. 8 A1).

OPERATION. Pressure on the head of the striker stem shears the shear wire and allows the striker spring to drive the striker into the percussion cap. The resultant flash passes through the flash channel and initiates the firing of the detonator and main charge.

EMPLOYMENT. This igniter was manufactured by the Germans for use in the British anti-tank mines Mk. 3.
