Abstract
A trigger mechanism for electrically ignited weapons having a source of electric energy. Leads are provided which connect the source of energy with the electrical ignition means for a propelling charge contained in the weapon, and a normally open switch is interposed in one of said leads, which switch can be closed for igniting the ignition means by pulling the trigger. The source of energy comprises a piezoelectric body and a capacitor connected in parallel with the piezoelectric body, the trigger being coupled with a striker which is tripped from a tensioned position when the trigger is pulled and released for striking the piezoelectric body before the switch closes. The leads are connected with the capacitor and a diode is arranged between the piezoelectric body and the capacitor, the polarity thereof being such that the charge produced as a result of the blow of the striker against the piezoelectric body flows into the capacitor but cannot flow back from the capacitor to the piezoelectric body and the electrical energy stored in the capacitor is available for igniting the ignition means when the switch subsequently closes.
