Trigger mechanism for electrically ignited weapons

A trigger mechanism for electrically ignited weapons having a source of electric energy and electrical ignition means, leads connecting the source of energy with the electrical ignition means for a propelling charge contained in the weapon, a trigger, and a normally open switch which is interposed in one of said leads and which can be closed for igniting said ignition means by pulling the trigger, in which said source of energy comprises a piezoelectric body and a capacitor connected in parallel with said piezoelectric body, in which said trigger is coupled with a striker which is tripped from a tensioned position when said trigger is pulled and released for striking said piezoelectric body before said switch closes, and in which said leads are connected with said capacitor and a diode is arranged between said piezoelectric body and said capacitor, the polarity thereof being such that the charge produced as a result of the blow of said striker against said piezoelectric body flows into said capacitor but cannot flow back from said capacitor to said piezoelectric body and the electrical energy stored in said capacitor is available for igniting said ignition means when said switch subsequently closes, said piezoelectric body being connected with a voltage doubling circuit comprising two capacitors connected both in series and individually parallel with said piezoelectric body via diodes in such a manner that, depending upon the polarity of the charge produced, either the one or the other of said capacitors is charged.
