Abstract
An annular impact switch for activating the electrical firing circuit of a uided projectile. An annular base member formed from thermoplastic is fixedly secured within the nose of the guided projectile. An annular crushable member formed from thermoplastic is mated to the annular base member. Both members are selectively coated with a multi-layered electrically-conductive film; a spatial separation between the electrically-conductive films coating the annular base member and the annular crushable member maintains the electrical firing circuit in an open state. Upon impact with a target the annular crushable member is deformed into contact with the annular base member such that their respective electrically-conductive films are in electrical contact to close the electrical firing circuit of the projectile, detonating the projectile explosive.
