AI Technical Summary
Technical Problem
In traditional button devices, the keycaps of longer buttons are prone to causing delays or failures when pressed at the corners, and the pressing feel is inconsistent.
Method used
First and second elastic bodies are respectively set in the middle and side pressing sections of the keycap. By using different trigger switch designs, the consistency of the pressing trigger time is ensured, and by controlling the ratio of vertical distance to trigger stroke between 0.6 and 0.95, a consistent pressing feel is provided.
Benefits of technology
It solves the problems of button trigger delay and failure, and improves the consistency and sensitivity of the pressing feel.

Abstract
本发明公开一种按键装置包含键帽、底板、薄膜电路板、第一及第二弹性体。薄膜电路板设置于底板上且与键帽的帽缘底面相距按压行程。第一弹性体设置于键帽的中间按压区段与薄膜电路板之间，以于中间按压区段被按压时挠曲变形而触发薄膜电路板的第一触发开关。第二弹性体设置于键帽的侧边按压区段与薄膜电路板之间。当键帽未被按压时，第二弹性体与键帽的按压底面相距垂直距离。当按压底面接触第二弹性体且继续下压触发行程时，第二弹性体挠曲变形以抵压触发薄膜电路板的第二触发开关。垂直距离与触发行程的和除以按压行程的比值介于0.6～0.95之间。本发明可避免倍数按键在键帽边角被按压时造成按键按压触发延迟同时提升按压手感。
