Abstract
A solenoid-operated device, and especially a weapon-arming device, subject to inertial forces is provided in which the solenoid armature is operatively coupled to a counterbalancing mass operatively constrained to move in synchronism with but oppositely to the armature, inertial forces on the armature acting equally and oppositely on the counterbalancing mass. The counterbalancing mass surrounds the solenoid coaxially and has an annular extension provided internally with rack teeth that mesh with sprockets free to rotate on fixed pins, these sprockets also being in mesh with rack teeth on an extension of the armature. An armature retraction spring bears on a shoulder on the counterbalancing mass.
