This element is a delay, chemical-electrical type fuze containing a spring-loaded striker with a chemical release. Internally, it is similar to the EKhV fuze. It is housed in a cylindrical tar impregnated cardboard container. Two electric lead wires project from one end of the fuze. One green-covered wire and one red-covered wire project from the other end of the fuze. There are two sizes of this fuze. The larger size is 5 inches in length and 1 3/8 inches in diameter, while the smaller size is 2 inches in length and 5/8 inch in diameter.
This fuze is used as a safety delay element in any electric detonating circuit for providing delay from 10 minutes to 4 hours with the smaller fuze and up to 4 months with the larger fuze (temperature affects the delay, the lower the temperature the longer the delay). The fuze is employed in the MZD-4 delayed-action mine.
When connected to a battery in an electric detonating circuit as shown in figure 40, electrolysis begins. After a time lapse, the striker-retaining wire is eroded, thus releasing the striker and closing the circuit.
