Abstract: A variable time fuze for a gun launched projectile comprises a digital electronic counter which is preset by insertion of a coded key into a slot within which are spring loaded contacts. The number which is preset in the counter depends on the pattern of conductive and non-conductive areas inscribed on the key. A clock circuit provides pulses to the counter which initiates a squib-firing network when the preset number is reached. Time delay circuits are provided to prevent accidental firing of the squib, to strobe the preset number into the counter and to allow the counter to stabilize before application of the clock pulses.
