High-life mute micro-switch

Abstract

The invention discloses a high-life mute micro-switch, which comprises a base, a cover covering the base, an elastic body and a flexible body, wherein the cover covers the base to form an accommodating cavity; a guide core is arranged in the accommodating cavity; an upper opening through which the upper end of the guide core passes is formed in the cover; the elastic body is arranged in the accommodating cavity and is located at the lower part of the guide core; the flexible body is arranged on the lower end surface of the cover and is located at the upper part of one end of the elastic body;a plurality of upper elastic strips are arranged at one end of the elastic body in a manner of extending upwards; the plurality of upper elastic strips are located below the flexible body; and when pressing on the guide core is released, the elastic body rebounds due to deformation recovery, and the upper elastic strips are prompted to touch the flexible body and flexibly deform, so that the impact force is reduced through generated buffer force to achieve the muting effect. The micro-switch disclosed by the invention has the muting function, a good muting effect is achieved, and meanwhile, the whole life is prolonged and reaches 80,000,000 times.

Description

technical field [0001] The invention relates to a micro switch, in particular to a high-life silent micro switch. Background technique [0002] Micro switch is a commonly used switch mechanism. It is a contact mechanism with a small contact interval and a quick action mechanism that performs switching actions with a specified stroke and a specified force. It is widely used in industry, electronics, machinery, and governance. Gold, electricity and other fields. [0003] The working principle of the existing micro switch is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and when the action reed moves to the critical point, an instantaneous action is generated to make the action The moving contact at the end of the reed is quickly connected or disconnected from the static contact. [0004] The existing micro switch usually adopts the method of setting the movable contact on the action reed. Bef...

Problems solved by technology

With this conduction method, because the micro switch is often applied with a large pressing force, the corresponding action reed has a large elastic recovery force. During the two processes of its up and down bouncing, due to the relatively large force, It will generate a large force on the base and the cover, and will naturally make a loud sound, resulting in a loud sound during the process of pressing up and down, which is not suitable for a quieter environment

[0005] At the same time, due to the limitations of the existing action reed molding process and structure, the action reed is easy to wear and has a short lifespan. The general life span is only 10 million times.
