Abstract
A cantilever feedback mechanism includes an upper cantilever and a lower cantilever. The upper cantilever and lower cantilever have a resistance spring rate to facilitate movement of the bellows over a selected range of resistances. The upper cantilever has downwardly oriented upper cantilever stops. The lower cantilever has upwardly oriented lower cantilever stops that engage the upper cantilever stops. Mean are provided for applying a preload to maintain the lower cantilever stops and the upper cantilever stops engaged until a force urging movement exceeds the preload.
