They are made of PET material and have text and patterns for prompts. The metal dome is installed inside and assembled with PCB or FPC. When you press the key part on the surface with your finger, the key contact is electrically connected to the corresponding part of the contact point on the lower part, thereby transmitting instructions. Tactile dome switches provide many conveniences in product application. Tactile dome switches are easy to install and affordable, which makes Tactile dome switches very popular among manufacturers in large-scale mass production. At the same time, Tactile dome switches provide efficient and accurate tactile feedback in applications, allowing users to convey instructions better and faster, and at the same time allowing users to trigger specific operations. https://www.metal-domes.com/blog/2023/10/24/tactile-dome-switches-enhance-user-tactile-experience/
