Abstract
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.
