Antirebound performance that lasts: the piano spring is designed to provide strong antirebound action and fatigue resistance for reliable longterm operation. Stable rebound with vertical alignment: the impact rod is processed to ensure verticality, so even with 360degree rotation and impact, the rebound value remains consistent and stable. Durable, integrated housing: the housing is a single, integrated unit, keeping the guide key and support permanently secure without damage or detachment. Durable button with reliable actuation: the button uses a stretching process to resist detachment, providing consistent feel and longevity. precision, smooth operation: built with precision materials and a finely ground spherical zeroadjustment screw, improving the smoothness of both rebound and firing. Key components and materials: includes a piano spring and an impact rod, designed to work within an integrated housing for compact, reliable performance. Compatibility and fit: designed to fit standard rebound modules and actuation assemblies that require a compact, integrated housing with stable rebound characteristics. Use scenarios In automated production lines, as a reliable mechanism for pushbuttons or actuators that require repeatable rebound and long service life. In precision robotics or automation equipment, where consistent rebound and smooth triggering are essential for repeatable motion control. In industrial control panels or handheld tools, where a durable, precision rebound system improves feel, timing, and longevity.
