Abstract

Firing mode selector device for firearms, whose purpose is to establish the change of working regime from shot to shot to burst and vice versa, it is essentially characterized by a connecting rod that connects the trigger trigger with the piston retainer. Dragging and percussion of the projectile, which is displaceable longitudinally by said trigger against the tension of a spring that tends to keep the retentor projected towards the piston and joins jointedly to the retainer to cause the tilting thereof, having foreseen that the said connecting rod is constituted by two parallel arms stiffened together, through the pivot axis of the retainer, which is partially housed between them, and through a second shaft that is through a hole in the body of the trigger trigger, with the particularity that this hole adopts an L-shaped configuration with a substantially vertical branch when oriented upwards and slightly backwards and the other perpendicular to the first and oriented towards the rear, so that in a situation of rest for the trigger, said second axis is housed in the upper end area of the hole and its actuation supposes a drag for the connecting rod with the corresponding tilt of the retainer, followed by a translation of the shaft to the rear area of the orifice, accompanied by a slight tilting down of the connecting rod, with the consequent recovery by the connecting rod, with consequent recovery by the connecting rod of its internal longitudinal position and by the retainer of its locking position for the piston.
