Use:

The M605 fuze is used with the M16 series antipersonnel mines.



Description :

The M605 fuze is of the combination type, with a three-pronged pressure firing mechanism at the top and a pull wire release pin ring at the side. The firing mechanism is housed in a cylindrical, metal case which contains the cocking mechanism and a trigger pin, a release pin, and a firing pin, each fitted with a coil spring. The base or loading assembly contains a primer, a delay charge, a relay charge, and an igniter charge. Two safety pins render the fuze safe during shipment and handling. A cotter pin passes through the end of the release pin and bears against the body of the fuze. A second cotter pin passes through the end of the firing pin, between the prongs. An interlocking pin between the safety pins provides additional safety.
Fuzes are shipped with the M16 mines or as separate issue. A hexagonal shipping plug closes the fuze well of the mine. A fuzing wrench M25 is issued with the mine.

Functioning :

The M605 fuze is functioned either by a 3 to 15 pound pull on a trip wire or a force of 8 to 45 pounds on one or more of the prongs protruding from the top of the fuze. This pull, or push, releases the firing pin which strikes the primer, igniting the delay charge. The delay allows time for persons stepping on prongs to move from directly above the mine, where their presence might inhibit the proper functioning of the mine. The delay charge ignites the relay charge which, in turn, sets off the flash igniter charge. This charge ignites the expelling charge, the first element of the mine firing train.
