• the object of the invention is to find a multi-shot handgun with electric ignition, whose function is safer.
• the aforementioned weapon has a pivotable contact lever, whose pivotal movement is coupled to the movement of the closure, and which is in electrical contact with the firing pin and on the other hand with the electrical circuit, wherein it is designed such that it the electrical contact between the electrical circuit and the firing pin breaks when the shutter is open.
• the structure of such a weapon can be designed so that it does not differ externally and in the general operation of a conventional weapon.
• the contact lever therein resembles in particular a cock, which of the already only slightly opening closure is pivoted back and breaks the circuit to the firing pin as soon as the shutter has moved only a little backwards.
• the ignition contact is already interrupted before the weapon has unlocked.
• the contact lever may in turn lie within the weapon, as in a "cockerel" pistol or a self-loading rifle, but may also be exposed at the back so as to reduce the overall length of the weapon - a pistol. But since he does not need to be tense, he also does not have to be palpable by hand, so that he optionally fills a longitudinal slot on the back of the carriage of a pistol from which he only emerges during the reloading process. Accordingly, the pistol does not have a projection (the cock), such as a conventional faucet weapon, to which the weapon could catch when pulled or deployed.

• the contact lever is formed at its end abutting the firing pin so that the firing pin is no longer touched by the contact lever in the rearwardly moving shutter and thus there is no electrical connection between these components.
• the contact lever is pivotally mounted on a pivot axis, on the outside thereof in the region of this pivot axis an electrically conductive contact point is provided which cooperates with a sliding contact such that the contact point with the sliding contact is only in electrical connection when the contact lever in one Pivoting position is located, in which the shutter is closed.

• the contact lever and firing pin can be configured such that when the shutter is opened, the electrical contact between the contact lever and firing pin is interrupted.
• the firing pin is preferably axially movable relative to the closure between two positions, with its firing tip protrudes in the first position from the shock bottom of the closure and in the second position does not protrude from the shock bottom, a firing pin him in the first biased position.
• the contact lever is at the shutter closed at the rear end of the firing pin and is biased against this end with a contact lever spring whose spring force is greater than that of the firing pin spring.
• the contact lever is like a cock loaded by a spring to the front, so that after each charging vigorously on the firing pin strikes (possibly a Oxidanhaftung, dirt, etc. removed) and pushes the firing pin against the force of the firing pin spring from the closure bottom.
• contact levers are not associated with any catches, such as a conventional tap, that could dirty or break out. A hardening of the release or release of the shot by a detent failure is therefore not possible.
• the electrical circuit has a trigger detection means coupled to the trigger (e.g., in the form of a key switch or other proximity sensor) which activates the electrical circuit when the trigger is fully pulled.
• the trigger therefore has only a simple "trigger", which triggers the shot, so that the shot can be triggered without delay.
• the triggering time is shorter than that of a conventional pistol, in which after triggering the free flight of the hammer or firing pin yes takes time that is longer than the time required to heat the resistor in the electric primer.

• the recovery time of the ignition state is adjustable, so that the cadence of the continuous fire can be reduced almost arbitrarily. A continuous fire with a cadence of 150 rounds per minute is easily possible, which even with a pistol without stop shaft allows a reasonably accurate continuous fire, for example, when an opponent should be kept in cover.

• the trigger and release detection device By providing two in particular mechanically actuated push-button for the trigger and release detection device, one of which serves as a trigger and the other as a breaker, it is possible to make the function of the weapon simple and transparent, so that even common weapons mechanics fix faults can. Finally, it is not necessary for manufacturing defects to change the entire electrical circuit or electronics for each affected weapon, but it is sufficient to replace the corresponding element - the pushbutton or the trigger bar.

• the trigger can, if it is pushed by the trigger spring forward, are moved against the force so far back until ultimately the shot falls.
• a rearwardly directed pressure piece is arranged, which rests upon actuation of the trigger over an initial distance away against the handle and then only a further actuation of the trigger over a short distance and under increased spring force permits.

• the withdrawal force and / or the remaining withdrawal path after reaching the pressure point can be adjusted, in the simplest case by turning the pressure element within a threaded hole in the trigger blade.
