AI Technical Summary

Technical Problem

Existing tactile switches have significant noise issues during use, including friction or impact noise between the button and the dome switch, as well as metallic clanging noise during deformation, which affects the user experience.

Method used

A silicone pad is placed between the button and the dome switch, combined with an inverted funnel-shaped structure and a boss design. The damping properties of silicone are used to form a stepped buffer to absorb the impact of pressing. The independent contact part design optimizes the elastic deformation path and reduces noise.

Benefits of technology

It significantly reduces noise during the pressing process, improves the quietness and response efficiency of operation, extends service life, and avoids rebound jamming caused by long-term load.

Abstract

This utility model belongs to the field of switch technology, specifically a silent tactile switch, including a base and a top cover. The base is provided with a first contact and a second contact, both of which extend into the interior of the base. A dome switch is mounted on the base, including a connecting part and a contact part. The contact part is provided with a moving contact that mates with the second contact. The top cover is provided with a button that extends through the top. A silicone pad is provided between the button and the dome switch. The bottom end of the silicone pad has a protrusion that contacts the dome switch, and also has a vent hole and a positioning protrusion on the bottom circumference. The top of the base is provided with a positioning groove that mates with the positioning protrusion. The top cover and the base are riveted together. Through the above structural design, this utility model can effectively reduce pressing and rebound noise, improve the quietness of operation and response sensitivity, and extend the service life.
