Abstract

Described is a simple and effective way of actuating a ballistic print wire. Lever arm 10 is a die-formed cantilever-type spring that is positioned at a stationary fulcrum 12 and secured to armature 14 which holds the ballistic print wire. When electromagnet 16 actuates armature 14, the lever arm takes the position 18. When current is released from the electromagnet 16, spring-loaded plunger 20 pushes against the lever arm 10, allowing the armature 14 to rest at backstop 22.
