Abstract: A percussion device for a medium or large caliber weapon incorporating a firing pin, spring means and a drive cam for the firing pin enabling its displacement in translation up to an “armed” position and the compression of the spring means, such device wherein it incorporates means to immobilize the firing in the “armed” position, these means being supported by the weapon breech and able to take up a position in which they immobilize the firing pin and another in which they release the firing pin.

Abstract: A contact safety device between two mechanical parts mobile which respect to one another to guarantee the internal kinematics, by the release or activation of control means, wherein said device incorporates a safety unit connected to one of said two mechanical parts enclosing a probe activated by one of said two mechanical part and amplifying means constituted by an amplifying lever activated by said probe and an immobilizing lock activated by said amplifying lever meshed on said control means so as to transform a rectilinear micro-movement into a circular movement of large magnitude.
