The Chemical Fuze M600 is a separate unit and consists of the fuze body, piston, safety key. compression sleeve, resistance spring, vial of chemical, detonator, and fuze booster charge. The spring is cut away at either side, and the perforations in the sleeve are large so that the fuze itself may be activated by a force of 190 pounds. When the Belleville spring is inserted in a Mine M6, a pressure of 300 to 400 pounds is required to overcome its resistance.
When pressure is .applied on the pressure plate, it is transmitted to the piston head. As the resistance of the spring is overcome, the compression sleeve is crushed, and the piston moves down to crush the vial of chemical. The chemical reacts with the surrounding mixture to set off the detonator, fuze booster, booster, and main charge.
No information about hazardous components.
