SWITCHES WITH REDUCED NOISE FOR ELECTRONIC DEVICES

摘要

This application relates to a dome switch assembly including a base plate that carries a first contact, and a flexible surface connected to the base plate, the flexible surface formed of a metal material in the shape of a dome. The assembly can include a second contact coupled to the flexible surface, and a sound-dampening pad coupled to the flexible surface and formed of a material having noise-dampening properties, wherein when at least a threshold amount pressure is applied to the flexible surface, the flexible surface changes from the dome shape to a collapsed shape allowing the first and second contact to touch, wherein the sound dampening pad absorbs at least some acoustic energy emitted by the touching of the first and second contacts.
