ABSTRACT:
An electro-mechanical triggering mechanism for fire arms which comprises a signal receiver used as an input unit which converts a shot-triggering signal generated by the user pulling the trigger into an electrical signal and an electro-mechanical converter which forms an output unit, which unit receives the electrical signal from the input unit and acts on a shot-triggering element to initiate the shot. The improvement consists in that the electro-mechanical converter is an electrically or electro-magnetically deformable piezo-active element which is mechanically connected to the shot-triggering element to initiate the shot. The piezo-active element can be a cantilevered bending bar; a hollow body filled with piezo-active liquid which is capable of moving a piston or elastic membrane; or a bending bar having a series of longitudinally extending bores having electrically conductive walls throughout its middle. Moreover, the signal receiver can take the form of a potentiometer; variable capacitors; monolithically integrated touch key; piezo-resistive semi-conductor component; an inductive or capacitive approach switch; a photo-electric unit; or a semi-conductor element control by a magnetic field.
