spring action
Tension-powered movement response
Spring action refers to a mechanism that uses a coiled spring to store and release energy, providing quick, automatic movement.
The term appears in contexts from firearms to furniture: a spring action knife opens with a button press, a spring action hinge closes doors automatically.
The phrase emphasizes the snap or responsiveness that springs provide: The spring action on this stapler is satisfying.
