This is a modified version of the MUV pull fuze with an arming time delay device.
The delay gives the troops ample time to lay and camouflage a mine and reach a safe distance before the fuze becomes fully armed.
A thin cutting wire is attached in a groove across the protruding end of the striker.
Beneath the wire is a soft metal plate held in place by a sleeve fitted over the end of the striker.
When the safetypin is removed, the wire cuts through the soft metal plate.
The striker is then held only by the retaining pin.
A force of two pounds or more removes the striker retaining pin.
The spring drives the striker against the percussion cap, starting the firing chain.
