Abstract
Stabilizing systems are disclosed herein that can reduce the amount of noise produced by an input device and can contribute to a stable feeling in operation even with a short pushing stroke. In some embodiments, a stabilizer bar is coupled to a base plate by hooks with semi-circular cut-outs that allow the stabilizer bar to slide and tilt relative to the base plate. The stabilizer bar is also coupled to an input element by hooks having semi-circular cut-outs and a spring tab that allow the stabilizer bar to rotate relative to the input element. Bias forces generated by the spring tabs and the tension in the stabilizer bar maintain the bar in firm engagement with the hooks, preventing collisions and clattering noises during operation.
