In a combination fuze for missiles comprising a current generator which is driven by a ram air operated means having ram air supplied through an inlet in the nose portion of the missile and supplying electric energy to an electric firing circuit which comprises an electric detonator and means adapted to detonate the electric detonator before the missile reaches the target, and comprising a mechanical percussion switch adapted to cause detonation of the missile upon impingement of the missile against the target, the mechanical percussion switch comprises a sting sensitive detonator surrounded by a metal foil and a firing needle which is included in the electric firing circuit. Upon impact the relative movement between the firing needle and the sting sensitive detonator induces such a circuit configuration of the firing circuit that triggering of the electric detonator will take place. By using a jacket which partly or completely blocks the electric firing circuit the combination fuze may be operated with three various functions, i.e. as a proximity fuze with a first electric percussion function and a second mechanical percussion function as further securities for firing, as a percussion fuze having electric firing of the electric detonator with a mechanical percussion function as a further security for firing, as well as a percussion fuze with mechanical firing only. |
