What is the term for a striker or firing pin that is held under tension by a releasing mechanism?

The term for a striker or firing pin that is held under tension by a releasing mechanism is referred to as a "Cocked Striker." This term specifically describes a component in a firearm or explosive ordnance device where the striker is positioned in a state that is ready to be released. It is held back by a mechanism, often a spring, which, when actuated (for instance, by pulling a trigger), allows the striker to move forward and initiate the firing sequence.

In various EOD contexts, understanding the mechanics of strikers and how they interact with other components is crucial for safely disarming or neutralizing explosive devices. The cocked striker presents a state where the mechanism is primed for action, indicating potential energy that must be carefully managed during operations. Recognizing this term helps in comprehending how devices are designed to function and the precautions necessary when dealing with them.

The other options represent different components or concepts: a spring lock refers to a mechanism that securely holds a part in place until released, a trigger is the control that activates the firing mechanism but does not specify the state of tension of the striker, and a firing pin is the component that strikes the primer of a cartridge but is not itself described as being under tension by a
