A bi-stable or multi-stable device having two or more stable positions includes an elastically deformable member having two or more stable positions of minimal potential energy, the deformable member being movable, in response to an external force applied to the deformable member, between stable positions by moving through a position at which the deformable member has a peak potential energy. The device also includes an energy storage member, either separate from or part of the deformable member, that absorbs energy from the external force applied to the deformable member as the deformable member moves from a stable position toward a position of peak potential energy, and releases energy as the deformable member moves from a position of peak potential energy toward a stable position, wherein the energy storage member includes a super elastic shape memory alloy (SMA).
