The mechanism combines a bistable state element, a buckling column operating near bifurcation, and a nonlinear connecting spring. State-dependent mechanical interactions determine the subsequent transition without requiring separate actuation inputs.\u003cbr\u003eThe research combines analytical modeling, nonlinear finite element analysis (FEA), and experimental validation. An analytical spring-based rigid-body model was developed to identify the requirements for state switching. Numerical simulations using ANSYS APDL were performed to investigate the compliant mechanism, characterize its response, and identify influence of geometrical parameters. A monolithic prototype fabricated from polyamide-12 was experimentally characterized using force-displacement measurements and video-based displacement tracking.\u003cbr\u003eThe associated research data support the characterization of mechanical instabilities, switching thresholds, input-output kinematics, and the comparison between numerical predictions and experimental observations. The research provides a basis for developing state-dependent mechanical building blocks for adaptive
