Patent ID: 7661364

Claim:
A safety and arming unit ( 11 ) for a spinning projectile fuze ( 12 ), at least two pairs of resistive contacts ( 22 - 23 ) are provided offset peripherally with respect to one another about the circumference of the fuze ( 12 ) and connected electrically in parallel with one another, at least two spring-loaded bolts ( 17 ) which are spaced about the circumference of said fuze and are movable as a function of centrifugal force, each said bolt ( 17 ) having respectively one of the pairs of said resistive contacts ( 22 - 23 ) operatively associated therewith, and wherein each of the bolts ( 17 ) is movable against the force of a return spring ( 18 ) transversely with respect to the rotational and longitudinal axis ( 13 ) of the fuze ( 12 ) from an electrical short-circuit position past two of said resistive contacts( 22 - 23 ) which are connected in series with a safety circuit ( 24 ), such that an electrically conductive bridging of each respective pair of resistive contacts ( 22 - 23 ) by the herewith associated bolt ( 17 ) is interruptible responsive to the occurrence of the centrifugal force.
