Abstract

The invention provides a dustproof and dampproof touch switch. A flexible film, which adopts a convex structure and has a circular hole in the center of the bottom, is arranged in a shell; a support plate is arranged in the corresponding circular hole in the bottom of the flexible film; a spring is arranged above the support plate; the flexible film is tightly jacked to the shoulder part of the shell by the top of the spring; a metal elastic sheet and a pressing part are also arranged in the flexible film; and by setting the flexible film outside each component, the internal components can bewell protected, thereby preventing dust and water invasion.

Description

technical field [0001] The invention relates to an electrical component tact switch of an electronic circuit, in particular to a dust-proof and moisture-proof tact switch. Background technique [0002] The tact switch is also called the key switch. It is an electronic switch, which belongs to the category of electronic components. It first appeared in Japan. The switch is disconnected immediately, and its internal structure is realized by the force change of the metal shrapnel. Widely used in digital cameras, household appliances, and mechanical equipment and other fields. [0003] The waterproof, dustproof and waterproof performance of the tact switch is an important performance index of the tact switch. If dust or water enters the switch, it will cause corrosion of the metal shrapnel, and poor contact will occur after long-term use, which will eventually cause the switch to fail. Contents of the invention [0004] The invention provides a dust-proof and moisture-proof ...
