This fuze is especially designed for use with the OZM bounding fragmentation-type mines.
It consists of a cylindrical sheet metal case containing the propellant charge, a delay element, detonator, and a booster charge.
There are two holes in the device. One is usually closed by a plug for insertion of a flash tube if the assembly is to be fired by mechanical means; and the other is for the leads of an electric blasting cap, if it is to be fired electrically.
Electrical or mechanical ignition sets off the propellant charge, igniting the delay element.
The delay burns through to ignite the detonator, starting the firing chain.
