Description
This fuze is a delay, mechanical type where a handset clockwork release lever closes an electric circuit. It is a commercial alarm clock with a knife switch attached to the alarm mechanism on the back. A housing with two contact arms, each insulated from the other, is also attached to the back of the clock. Two terminals, each wired to one of the contact arms, project from the housing and are used to wire the clock into a detonating circuit.
The alarm clock can be used as the only fuze in an electric circuit or it can be used with an instantaneous electrical fuze, such as the PZ-12 railroad fuze.
Functioning
At the expiration of the preset time, the alarm mechanism trips the knife switch which closes the circuit between the two contact arms, thus exploding the detonator.
