This fuze is enclosed in a circular cardboard case.
The interior consists of a thick rubber hollowed out disk, in the center of which a Y-shaped metal vibrator is suspended by three fine spiral springs.
On the top is a contact screw that is attached to one of the electric wire leads.
The other wire lead is attached to one of the springs, so that the circuit is broken by only a short space between the vibrator and the contact screw.
The leads are connected to an electric circuit for the ignition of the charge.
Vibrations set up by passting traffic causes action in the fuze vibrator until it touches the contact screw, closing the circuit and firing the detonator.
The fuze is versatile enough to be used to detonate any type of charge or mine.
