    • A switch is adapted for use in a projectile for actuating an electrical explosives-igniter in response to impact of the projectile. The switch includes a stationary electrical contact and a movable electrical contact. An actuator moves the movable contact against the stationary contact to complete an electric circuit in response to projectile impact. The actuator comprises a ball movable toward the movable contact. The ball is seated in a conical recess to enable the ball to move toward the movable contact even when the projectile does not impact along its longitudinal axis. The movable contact may comprise a cone-like array of flexible arms which engage the ball; movement of the ball flexes one or more of the arms into engagement with the stationary contact. Alternatively, the movable contact may comprise a linearly movable bolt engaged by the ball. A movable weight may be positioned behind the ball and adapted to engage the ball upon projectile impact to urge the ball toward the movable contact.
    • 开关适于在弹丸中用于响应于弹丸的撞击来致动电炸药点火器。 开关包括固定的电触点和可移动的电触点。 执行器将可动触头移动到固定触点上,以响应于弹丸冲击而完成电路。 致动器包括可向可动触点移动的球。 球座落在锥形凹槽中,以使球能够朝向可动触点移动,即使当弹丸不沿其纵向轴线冲击时。 活动触点可以包括与球接合的柔性臂的锥形阵列; 球的运动使一个或多个臂弯曲成与固定触点接合。 或者,可动触头可以包括由球接合的线性可移动的螺栓。 可移动的重物可以定位在球后面,并且适于在弹丸撞击时接合球以将球推向可动触点。
