Abstract

A device for retaining or releasing a wire for arming projectile fuses is provided, including a hook which retains the ring of the arming wire when the electromagnet acts, against the return action of a spring, through the mobile armature connected to the lever oscillating about the shaft. A catch pivoting about said shaft may engage by its end, a bearing face of said hook so as to maintain this latter in a position retaining said ring. A finger is carried by said lever and abuts against said catch, in the direction which frees this latter from the bearing face of the hook, when the lever is returned by said spring in the case of inaction of the electromagnet. A spring maintains the catch in contact with said finger.
