Title (EN) SWITCHING DEVICE FOR ACTING UPON THE OPERATION MODE OF ELECTRIC IGNITION SYSTEMS,IN PARTICULAR SYSTEMS FOR AMMUNITION IGNITION
(FR) DISPOSITIF DE COMMUTATION POUR INFLUENCER LE MODE DE FONCTIONNEMENT DE SYSTEMES D"ALLUMAGE ELECTRIQUE, NOTAMMENT DE SYSTEMES D"ALLUMAGE DE MUNITION
Abstract: front page image
(EN)The switching device comprises a cavity (4) provided in a casing and which has, cross-sectionally, the shape of arc of a circle. A channel (6) leads to the vertex of the arc of a circle. A switch (7) is arranged in said channel and energizes a delay circuit (8) mounted in an ignition circuit (9) which effects the firing of an initiator (12). According to the position of the projectile and of the switching device, a ball is located, when firing, either at the vertex, or at the periphery of the arc of a circle. In the first case, the ball, which is subject to an acceleration generated by the shot, in the direction of the arrow, releases the switch (7) thereby energizing the delay circuit. In the second case, the ball remains blocked in the cavity (4) and the switch (7) is not actuated.
(FR)Le dispositif de commutation comprend une cavite (4) menagee dans un boitier et qui presente, en coupe transversale, la forme d"un secteur de cercle. Un canal (6) debouche au sommet du secteur de cercle. Dans ce canal est dispose un interrupteur (7) qui excite un circuit de retardement (8) monte dans un circuit d"allumage (9) assurant la mise a feu d"une amorce (12). Suivant la position du projectile et du dispositif de commutation, une bille se trouve, lors du tir, soit au sommet, soit a la peripherie du secteur de cercle. Dans le premier cas, la bille, qui est soumise en direction de la fleche a l"acceleration produite par le depart du coup, declenche l"interrupteur (7) et excite ainsi le circuit de retardement. Dans le deuxieme cas, la bille reste bloquee dans la cavite (4) et l"interrupteur (7) n"est pas actionne.
